Question What could be causing this?

[tkalfaoglu]

A customer complained that some of the mail they send from gmail never reaches their mailbox at our server.

I'm looking at the logs I hope these are all related.. (customer domain replaced with XXX)

Oct 4 09:36:04 ocean psa-pc-remote[58664]: 7A5ED11E1224: check-quota: stderr: SKIP

What could be causing that No SMTP AUTH... line? I assume it is related to mail from [email protected] to [email protected]..

To me this looks like 2 unrelated mail transactions:
The message with the queue-id D42DD11E1228 is the incoming mail from Google and the message with the queue-id 7A5ED11E1224 looks like another mail (outgoing mail, sent through your server).

Can you grep for "D42DD11E1228" in your maillog and post the results here?

Even if it is related, stderr: INFO means what it says, no action, just informative, SKIP means that a check was skipped because it is not relevant.
The other outcomes are PASS (what e.g. spf says), DEFER (greylisting uses this), STOP (message sent to spam), REJECT (sender in blacklist, SPF failed), DATA (more information), ERROR.

Hello tkalfaoglu
The log you've provided refers to 2 separated emails, please pay attention to queue_id written by postfix (D42DD11E1228 and 7A5ED11E1224).

Please collect full log for the message you're interested in: from `postfix/smtpd[...]: $TRACE_ID: ...` to last entry which is usual is `postfix/qmgr[...]: $TRACE_ID: removed`.
