Question

Unable to send mail but can receive.Error Incorrect Greeting

Sad
I'm generally pretty good with a PC and the many issues that can happen. Even was tech support at one time but this has got me stumped.
It seems I can no longer send mail this started happening just a couple weeks ago .
The error mesg changes slightly on each attempt to send.

An Error occurred while sending mail: The Mail server sent an incorrect greeting: Eastmimpo109 cox connection refused from XX.xxx.xxx.xx (X's for my ip,address)

It would change the Eastmimpo 109 to 209 or 309

Just started getting different one's

An error occurred while sending mail: The mail server sent an incorrect greeting: fed1rmimpo209 cox connection refused from xx.xxx.xxx.xx (X's for my actual Ip addy)


I don't know how to fix this but I suspect that something is blocking my mail from being sent out on my PC. I talked to cox support at length and a t2 person said that they haven't seen a message even try to be sent from my account on their server in the last 3 weeks.

This first started happening using Outlook 2010 so I then installed Mozilla ThunderBird and it still happens here.

on my cox mail setup as they list on their site and what was told to me by tech support and no matter what I put in the mail fails.

Cox Server Names Settings imap.cox.net Incoming IMAP Port: 993 with SSL enabled and check the authentication box, if available pop.cox.net Incoming POP Port: 995 smtp.cox.net
Outgoing SMTP Port:
587 with TLS enabled
465 with SSL enabled and check the authentication box, if available

Note: Cox does not recommend the use of unsecure ports.


T2 tech had me go into safe mode and after a time she suggested using port 25 with NO encryption settings. And I was able to send a messg. This was in safe mode and only using port 25 using the regular setting it failed in safe mode.

This is what makes me think it's on my end because back in normal mode it wouldn't work.

There are lots of programs that will find Open or unused ports on a PC but I've yet to find one that will show you the ports used by a PC.

I have changed my PW with my ISP several times and that failed to resolve this.

I'm using Avast! and I turned it off for an hour while I worked on it with the T2 rep, and that didn't help or change things.
And the mail shield in Avast is NOT installed.
Using Avast! Premier 2015

My Router is a ASUS router and again working with the T2 tech at cox I disconnected it and connected my PC directly into the Modem. I use RJ45 cable connects to my Router both for my PC and Playstation 3. I also updated the router software and reset the router and all to no avail....or change in the error.
The router also is not broadcasting and does not or is not set up for wifi use.

And another thing... I recently installed a Epson all in one printer-scaner - etc
(model XP-310)
Went into services and stopped all that refereed to Epson and still no change in sending mail get same error.

Answer
For this to work

You would have to be on a Cox network.

A rather long discussion ended when the member revealed they were in Spain.

However the fact that mail shield is installed is a bad thing. I've encountered situations where it was disabled yet still interfering. I had to remove that entirely then start over.

PS. The confuser?

Your post contained the settings for both IMAP and POP/SMTP. I can't know if you know to use one or the other. I've seen folk burn up over trying to use both.

- Collapse -
more info

No I know the difference between Pop and IMAP and we tried one or the other and both failed. Except once in Safe mode where I believe the T2 tech at cox allowed unsecured mail through for that one time.

As for Avast I can't remove the e-mail filter if I could I would because I know what you are talking about. I had a terrible time with it a long while back as it was marking spam for a lot of non-spam mail even those from family. I actually went into the registry and changed the dword value so that avast mail shield wouldn't run.

Now I just setup thumderbird to use my gmail account on my PC using thunderbird as the e-mail client rather than on the web. That worked and was able to send and receive mail.

But setting up and additional cox e-mail address (I can have up to 10 with cox at no extra charge) and that Failed with the same error I was getting with my org e-amil account with cox.

Actually you can

Actually you can use Cox e-mail from anywhere in the world ....so log as you use their WEB-Mail
in other words login on the cox web page prove you are who you say you are then go to my connection -> Internet Tools --> Webmail

By the way...I can send mail using the webmail on cox.net just not using ANY client on my pc.

- Collapse -
That points to issues with COX's server or

You are not on their network. I've found COX, ATT, and other email to be too unreliable for my taste. Here we are again.

So Gmail IMAP works?

Then one last thing. You must be on the COX network and COX's servers must be working or else it fails. I take it that COX's WEB Email is working with these accounts?

As presented it points to COX email server issues. Not your PC.

To test if it's your PC, you would have to try another PC.
Note: Edited for typo.

Yes I'm on cox network

Humm well yeah I'm on cox network....That's how I'm connected now .....*duh*
Also as I stated before I am able to Receive mail but I can't send mail .....so again That kind of means I'm on cox network doesn't it?

- Collapse -
It means

That you are repeating what I see when I'm not on their network. It allows receives but not sending. That symptom is so well done that I don't want to repeatedly repeat it.

To me this sounds like they are having issues.

- Collapse -
really? Then why only me

I've called Cox support on several different days over the course of a week.

If they had a problem then why is it just me?

- Collapse -
Because they have many many systems.

They have tons of gear out there so one wrong entry on their gear and blammo.

It's not a new issue. It's happened before. I take it that no PC on your router can do this email? I can't guess what you don't tell but your top post is a confuser since why would you supply both IMAP and POP/SMPT? We must choose one or the other and enable which we use up on the email setup (Google and Yahoo for example may be an example here.)

I'm not there to check your work but the story so far sounds like it's a COX issue.

- Collapse -
OMG are you not reading?

The info up top is for one or the other and you can ONLY set it up for one or the other.
Using IMAP as an incoming server port 993 and ....what for it ....
Duh.....
using either one of the suggested ports for Outgoing FAILS !!!!!
Outgoing SMTP Port:
587 with TLS enabled
or this (you can't setup and select them Both there at the same time......)
465 with SSL enabled and check the authentication box, if available


The Outgoing server has to be SMTP when using IMAP....

Yes of course silly me Cox has the issue and the issue they have is just with me and just with my connection and just for my house ....because they decided to single me out ....*SIGH*

Getting help from here appears to be hopeless. All your going to do is say it;s on their end....when you have nothing to base that on.
I understand it's an easy out for you rather than actually helping, you can blame the ISP and they can't defend it or disprove it because they arn't here to counter your wild clam. You might just as well claim it's god's fault or Satan's because who's going to prove otherwise.

- Collapse -
OMGs!

"The Outgoing server has to be SMTP when using IMAP...."

This is why I focused on why you supplied both IMAP and POP. I know this is very frustrating but I'll try anyway.


->> HERE'S A THING. SSL is a dead thing.
https://www.google.com/#q=ssl+smtp+dead+

I wonder if their web site is out of date.

Another post wrote " SSL is DEAD. In Outlook just change the More settings to TLS instead of None. Simple " I'm unsure what settings you tried but maybe they killed SSL and didn't tell support?

- Collapse -
Re: mail

I read the whole thread, and nowhere i read if you can set it up working on your laptop (or the laptop of a friend) that is connected to your router or directly to your modem, or even using Linux on your PC.

That of course is the fool-proof way to find out if it's an issue in your Windows on your PC only (then the next step is to go back to your latest image that still works or to factory conditions) or if it's in the modem, the Internet connection or with Cox.
And it's an equally fool-proof way to show Bob he's wrong when claiming, based upon nothing, that it's a Cox issue.

Is this enough help for the moment?

Kees

Note: typo corrected. Thanks, Bob, for telling. But the rest of your answer is mysterious.

Is "fookly-proof" a thing in your country?

I think this member and I are about to have a moment. SSL is dead now so I wonder if someone at COX didn't get the memo.

- Collapse -
Did you miss it when

Did you miss it when I said I tried using the other setting....

587 with TLS enabled.... or is that dead too.?.

But never mind that if I set it ti use STARTTLS it fails with the exact same error ...(Omg really?)

of course it is silly me ...
We need to go to a CAC reader system that's much more reliable....

I asked it before and I'll ask it again, there are many programs to find open or unused ports are there any that show the used ports....I ask because just maybe something has taken over the use of the ports that are needed to send mail.

- Collapse -
OPEN PORT SCANNERS

I haven't used one in over a year. You should try them but for me I head to the router and turn off filters for test runs.

NOW THAT YOU ASKED, I went out and found other folk griping about COX email sending problems. You are not alone here. I may not be there to see every step you tried but as it stands it sounds like a COX issue.

If your router is non-stock I can't know that. That is, one client answered a question about security with "Maximum Security" from their router. What a mess. To me that's not stock.

- Collapse -
I bypassed the router

As I mentioned in the first post.
In working with the T2 tech at cox I disconnected the router completely and only connected to the cable Modem.....and the problem still persisted.


SO with the router not in the picture at all I elimated that from being an issue, but to be on the same side I updated the software and no change.
I then rest the modem to factory default, no change ....

So I think perhaps the router is not the cause here.

All signs are pointing to COX

I added the downdetector links.

There's one last thing. Another PC. But all signs tell me it's not just you or your PC.

- Collapse -
This is the ONLY PC I have

This is the ONLY PC I have at the moment. I don't have a Smart phone either or a cell phone for that matter

It's a good PC running win7 Ultra . 16 Gigs of Ram....etc. And is up to date with all MS updates and Avast updates.

A neighbor does have a laptop and I've helped him some, So I tell ya what when he comes home from work tonight (he lives alone as do I)

I will ask him to borrow his laptop and then connect here and setup a simple e-mail client such as Outlook Express or Thunderbird.

That should satisfy you I hope.

Yes of course lets format and reload the PC because if you can't find the answer then reload....*sigh*
I hate that suggestion as it's the lowest common denominator to use rather than find out what actually caused it (the error) in the first place.

Sorry but COX failed here.

This to me reads it's all COX now.

For me to test this I would carry in my own laptop, and try the IMAP and TLS settings.

You seem intent on that it's something that can be fixed but COX outages and their support that flat out don't know (or lie) is legendary.

Here I had some small hope it was this or that but your GMAIL TEST tells me it's COX or something very odd about your network. WHY DID I JUST WRITE ABOUT YOUR NETWORK? That question about open ports. If the GMAIL works, COX should have as well. Unless your router is set oddly.

- Collapse -
Just tell me what to select

Just tell me what to select and I will but I think I've tried every possible combination.

- Collapse -
Then there's this.

"Cox now admits there is an email problem but does not give an ETA on a fix (must be a backlog in India). Over the last several weeks, ours comes and goes. One email address works, others don't. My main email has been down for 3 days, even that email's Cox webmail site does not work. We pay way too much for this inconvenience."

At least the webmail is up. COX is well known to not have support folk that can tell if it's up or down.

My advice? Do not tie yourself to COX email.

- Collapse -
And this.
- Collapse -
Ok we'll see then

I am quite sure my neighbor will let me borrow one of his laptops. I fixed one he was having problems with and he has a second one he uses as well. So one or the other should be fine for me to test this issue of mine or cox as the case may or may not be.

I am quite certain that if I can or can't send from the second PC that would answer it one way or the other.

Answer
I've had this happen before

I have roadrunner email with Bright House. Which I can use POP3 or IMAP. With IMAP I just setup up to point to the email server and it handles incoming and out going. When I setup up POP3 I have to set up a Incoming setting and mine is incoming server is pop-server.cfl.rr.com security none and port 100 (which is the default). Outgoing SMTP. Well in the past my provider gave instructions to setup the outgoing server as smtp-server.cfl.rr.com. But on the server I could only send mail on the (CFL - Central Florida) network. When I travel to Ohio it wouldn't let me send outgoing mail when on the (NEO - NE Ohio) but i could receive. The a few years ago roadrunner set up a SMTPthat lets be send outgoing anywhere. The settings are mobile-smtp-roadrunner.com no security port 587 and requires a sign on. Using the SMTP-server.cfl.rr.com didn't require a sign on.

I got all those setting from the Bright House

website on configuring email so I would check to see if something changed with Cox.
