[Cialug] Email problems

[L. V. Lammert]

We had a great discussion a few months about on troubleshooting email
problems, have not had any until today. Testing is problematic, as these
are incoming emails, .. not outgoing, so they cannot be resent to test.

It appears that there is an Apple server with a problem:

Sep 27 18:33:21 Mail sm-mta[3073]: r8RNXLlF003073: ruleset=CheckMessageId,
arg1=<1584574278.31964481380324196632.JavaMail.email.apple.com>,
relay=mx2.omnitec.net [206.197.251.201], reject=553 5.0.0 Header Error

A 553 error is not "Header Error", .. any thought on determining the
cause?

	Thanks!
