Zimbra / Amavis blocking attachments

Dear MagicSpam-Team,

it is no longer possible to send out mails with a pdf attachment, due to the following error message:

Sep 1 16:27:42 mail amavis[23313]: (23313-01) do_notify_and_quarantine: spam level exceeds quarantine cutoff level 11
Sep 1 16:27:42 mail amavis[23313]: (23313-01) Blocked SPAM {DiscardedOutbound}, ORIGINATING_POST/MYNETS LOCAL [127.0.0.1]

We are currently running Zimbra [Release 8.8.15_GA_4362.RHEL8_64_20220721104405 RHEL8_64 FOSS edition, Patch 8.8.15_P41] with MagicSpam [2.1-14.3].

Disabling MagicSpam does not resolve the issue, only after uninstalling MagicSpam, e-mails get sent out correctly again.

Please urgently advise us on this issue.

Old post (sorry we didn't catch it earlier!).

Those log lines have nothing to do with MagicSpam. They appear to be strictly related to Amavis - which I believe runs SpamAssassin scans among others. From the looks of it, you have Zimbra configured to discard messages once they reach a certain spamassassin score (looks like 11 or more).

You will need to refer to Zimbra documentation to determine how to fine tune those settings, and/or how to figure out the cause of such a high score.
