I've a question about entries in yesterday's mail log for those of you who
professionally administer mail servers running postfix.
One reason postfix rejects incoming mail is a server configuration error
(the originating server, if I'm not mistaken). Many of these messages come
from servers hosting mail lists to which I'm subscribed and I don't
understand why some messages are received and others rejected.
Here's a redacted list of originating servers from yesterday's log:
Client host rejected: Server configuration error (total: 477)
34 hypatia.math.ethz.ch
31 google.com
31 sailthru.com
27 postgresql.org
19 linkedin.com
14 sqlite.org
7 memphis.edu
4 osuosl.org
1 nytimes.com
The first domain hosts the R maillist, the third a message from the
Washington Post, the seventh the LyX/LaTeX maillist; the others are
similarly legitimate originators. Unless someone has spoofed these domain
names when sending spam, I presume.
Please inform me about what might cause these messages to be rejected.
Rich
