Hi,

We've recently migrated to eFa V5 using the migration guide from eFa V4 and we've noticed an uptick in emails getting logged as spam. We'd normally get like ~5 emails a day in spam but we are now getting upwards of ~40

If we've done a backup and restore my thoughts would be that the spam filtering through would be the same. So I was wondering if there would be any other reason for this increase?

Thanks in advance for any help

Are the emails being blocked actually spam?

eFa5 includes SpamAssassin 4.0, which may explain the increase in flagged emails. I would expect it to be performing better than previous versions of eFa.

For the most part is is spam. So that part is a non-issue

We are however noticing an increase in automatic reply emails with no sender going into spam, then needing release before being sent.

Is this to be expected or not?

Automatic replies with no sender are tricky. These tend to come from mailer-daemons when emails bounce (soft-fail or perm-fail) from MTAs. MailScanner tries to detect them with a watermark in the header, but oftentimes that gets stripped out. If you are having trouble with this, you can try changing the following setting in /etc/MailScanner/MailScanner.conf:
