I am running qmail on a Slack(3.6)-Linux 2.2.7 dual pentium machine.
Recently a local administrator upgraded his Macintosh server to the
following:
Mac PPC 7200
Sys 8.1
Open Transport 1.3
TCP/IP 1.3
Eudora Internet Mail Server (EIMS) 2.2
After this upgrade email sent from his server to any alias on my server
would bounce with the following message (this is the message people would
receive on HIS server):
"After one day the following message could not be delivered to
[EMAIL PROTECTED] at host my.alias.edu. The last attempt to send this
message failed because no answer was returned by a DNS."
Sorry, I don't have header information to send along, though I noted the
following:
1) problem only started to occur after his upgrade
2) problem does NOT occur with any other server sending mail to aliases on
my linux box
3) DNS configurations and MX records are correct and have NOT been changed
within the past three weeks (problem started just over a week ago).
4) messages take almost a day to bounce back to his server (the Mac).
5) No error messages or even proof of existence is found on my linux box
for the bounced email messages, they simply are not getting through the
server to my end.
We were able to get a workaround going in which he rerouted mail to
my aliases to another smtp server. My questions are as follows:
1) Are there any known conflicts with qmail and the above Mac system? (I
realise qmail may get along nice with the Mac and no vice versa, my
counterpart in posting the same questions to a Mac MTA discussion list)
2) Potential solutions, or other potential sources that I should look at.
I am new to troubleshooting MTA problems on this system so if information
above needs more depth or doesn't make sense let me know and I can
clarify, any and all help is greatly appreciated!!
Thanks in advance,
Frank
