I love Gmail. I've been using it for over 6 years and wouldn't trade my account for any other webmail service.
However, lately I've been having a major problem with delivery delays when sending to a person that has an Earthlink account.
Sending the email is fine but the mail does not arrive in the recipient's mailbox for many hours, and sometimes days. Oftentimes, I receive an email back from the mail daemon that says:
Mail Delivery Subsystem to me show details 2:17 PM (5 minutes ago) This is an automatically generated Delivery Status Notification
THIS IS A WARNING MESSAGE ONLY.
YOU DO NOT NEED TO RESEND YOUR MESSAGE.
Delivery to the following recipient has been delayed:
Message will be retried for 2 more day(s)
Technical details of temporary failure: The recipient server did not accept our requests to connect. Learn more at http://mail.google.com/support/bin/answer.py?answer=7720 [mx00-dom.earthlink.net. (10): Connection timed out] [mx01-dom.earthlink.net. (10): Connection timed out]
I'm not sure why this is happening, especially since I've been emailing this person for years without any delays – but now it happens almost every time I email her.
Any help would be very much appreciated. I can share headers if that would assist in finding a solution.
