I use a dial up at my office (attglobal.net) and a cable ISP at home (cox.net). For the past couple months, whenever I send an email from attglobal to any cox.net address, it either gets there 18 to 24 hours later or sometimes not at all. I can send from attglobal to any other ISP and it usually get there in seconds. I have spent several hours on the phone with both cox & attglobal support with no luck.
At this point, I am trying to figure out if I should bail on attglobal (I have used them for over 10 years). I sure would like to resolve this problem if anyone has any ideas. Below is a header from one of the emails that got returned:
