As to preventing it, I don't want to sound dismissive but the only way to avoid it is to keep more than one email account open to send with. So when blocks happen you can send another way.
I also will defer to the big web about blacklists and investigating blocks. You will have to invest a lot of time to find out where it failed and no one will tell you if you can fix it. In fact I have rarely heard of anyone fixing a blacklisted server or email address.
Hi, (thank you in advance for the help!)
- I was trying to send a very important business email this morning. I have used their email several times in the past- and was replying to a message they had sent me... i am 100% sure their email was correct no typos etc.
However after i sent the email about 30 min later i received an email from email@example.com saying the following:
( I have an aol account- the reciver used an @theirbusinessname.com account;.
"This is the mail system at host omr-m09e.m.aol.com.
I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.
If you do so, please include this problem report. You can
delete your own text from the attached returned message.
The mail system: connection timed out"
below was a bunch of coding.
I tried to send the email 2 more times and received the same kick back.
I later used my GMAIL account and the message was sent successfully and i got a reply from the receiver.
my question is:
1) Why did i receive a bounce back email?
2) did the receiver get my multiple messages from aol? (hoping not since i did not want them to receive it more than once.)
3) once they get bounced back does the server automatically attempt to send the messages again? - again i do not want these messages to go through now that i used my gmail. its a business related message and would be extremely embarrassing to have sent multiple messages, especially from various accounts.
trying to make sure this does not happen in the future- was very frustrating. thank you!!
