I have a mailman list running on Linux CentOS 5 with sendmail 8.13.8.
Generally, everything works (I believe/hope).
Today I got a bounce action notification. When I looked at it,
there's a regular DSN e.g.
----- The following addresses had permanent fatal errors -----
<x...@utvinternet.com>
(reason: 550 5.1.1 <x...@utvinternet.com>: Recipient address rejected: User
unknown)
OK so far. Then in the same message I see
----- Transcript of session follows -----
... while talking to gmail-smtp-in.l.google.com.:
DATA
<<< 451-4.3.0 Multiple destination domains per transaction is unsupported.
Please
<<< 451 4.3.0 try again. r2si3773706igh.8 - gsmtp
<use...@gmail.com>... Deferred: 451-4.3.0 Multiple destination domains
per transaction is unsupported. Please

Please

<use...@gmail.com>... Deferred: 451-4.3.0 Multiple destination domains

etc.
When I grep the mail logs, all the deferred messages to
gmail-smtp-in.l.google.com (74.125.192.27) are x...@gmail.com,
i.e. all to gmail.com
However, I've also got several users on googlemail.com, also using
74.125.192.27. Those messages went through OK, and seem to be associated
with the ID r2si3773706igh.8
Has anyone else seen this ? Does Google not like sendmail anymore ?
A bit later, I see things like
to=<user...@hotmail.com> dsn=4.3.1, stat=Deferred: 452 Too many recipients
to=<user...@hotmail.com> dsn=4.3.1, stat=Deferred: 452 Too many recipients
Again, does Hotmail not like sendmail ? Is there something I should tune,
or is this just normal mail behaviour and it will be dlayed till the next
queue run ?
