It may be coincidental, but suddenly my two co-workers can no longer send
mail using SMTP-AUTH. They haven't changed anything on their clients, but
the network they are on had some sort of firewall installed (we sub-lease
space and are on their network). They claim that they don't block anything
going out, but I can't come up with any other explanation other than they
are messing SOMETHING up. The error they get is 550:
The message could not be sent because one of the recipients was rejected by
the server. Server Response 550 not local host alum.rpi.edu, not a gateway.
(Account: Worlds Email, SMTP Server: mail.worlds.net, Error Number 0x800ccc79)
The email client is Outlook for one user, and Outlook Express for the other.
We have relaying turned off except for SMTP-AUTH users.
Anyone seem anything like this before? One user is going to take her laptop
home and see if SMTP-AUTH works from home, which will firmly point the finger
at the firewall -- but what on a firewall would cause this behavior???
