If this isn't the right forum to discuss this, please let me know and I'll post it in the correct one!
Years ago our company had our website (fairmont.org) hosted by Charter Communications. A .domains file was setup to forward email addresses sent to
someone@fairmont.org on to their correct POP3 email account through Charter. There were probably 2 dozen aliases, including a catchall that went to my default email (mjfmn@chartermi.net). Good setup, worked fine.
About 2 years ago we switched to a new hosting service who did all the forwarding through their "system", whatever it is. Either way, there was no more .domains to maintain, I told them where to forward emails. Naturally, the POP3 emails were all changed over to the new host and it's worked great!
EXCEPT: Once in a great while someone tells me an email was bounced back to them stating that the "mjfmn@chartermi.net" account did not exist. They are sending emails to legitimate, working email addresses that work fine! I double-checked my website to make absolutely sure there wasn't ANY .domains file on the place, and there isn't! The new host swears that the email address doesn't exist on their system either.
This is a very sporadic problem. Is there another reason why this would crop up once in a while? Is there a "cache" out there somewhere still storing the old, now dead email address?
Thanks for any and all help!
