this was my problem:
I have installed patch 105465-02 on a SunOS 4.1.x host. This sendmail V8
for SunOS 4.1x from Sun.
I see now sometimes messages like this:
Jan 5 13:14:50 popeye sendmail: NAA12202: SMTP MAIL protocol error: 501 Unknown domain 'popeye'
Jan 5 14:19:12 popeye sendmail: OAA12518: SMTP MAIL protocol error: 501 Unknown domain 'popeye'
J an 5 17:12:02 popeye sendmail: RAA13277: SMTP MAIL protocol error: 501 Unknown domain 'popeye'
First question: Where can i find the man page for sendmail error messages (for
this Sun V8 version) ???
Second question: Has somebody a hint for this problem?
Well i have changed the Cm line in sendmail.cf and changed some entrys
in /etc/hosts. Some problems are now disappeared. But i don't know, what the
problems are. I will wait and see. The sendmail configuration
is very old here, so i have to check it now a little bit more.
Error messages, well, sometimes it is very helpful to look in RFCs .... ;-)
I have found a nice webserver with TCP/IP docs:
There you can find some RFCs and docs, for example about mail/smtp:
I hope this links helps others.
