[pop3] Sagesite.utmb.edu SMTP problems

[Mohammed R. Arjomandi]

Dears,

My recent sent e-mails through SMTP of sagesite.utmb.edu are coming back,
with "Unable to deliver the message for past ... days" responce.

I know that the destination addresses are working, as I'm able to send them
from my other addresses without any problem or bounce. Does Anybody else
have noticed this?

Thanks,
Mohammed
