Hello,

EFA seems to be running fine for the most part. The bulk of emails are processed and delivered normally.

We have 600+ messages building in the Milter Outbound on 2 different EFA servers going back to Nov 2021.

What can I do to determine the cause of the queue building?

How do I release the emails in the Milter Outbound queue?

Thanks!

Todd

First question, what version of MailScanner are you on?

Sorry I should know better. eFa 4.0.4

MailScanner 5.4.2-3.eFa.e17.noarch

So, this has me concerned. The fact that you mention when it started is vital.

Back in Nov 2021, this change was made:

Limit queue processing to child-owned queue files in MSMail.pm

So, your theory about restarts is plausible. If the child stops or dies before before processing the files it owns, this would be a problem.

I am going to check into this. https://github.com/MailScanner/v5/issues/591

In the meantime, please move any orphaned files from /var/spool/MailScanner/milterout to /var/spool/MailScanner/milterin to requeue.

Thanks for the update Shawn.

I am reasonably sure this has to do with restarting services. I have been performing this restart of the services for many years, since we first started with EFA, and dont recall ever having this problem in the past.

I have 3 EFA boxes and I configured 1x to only restart postfix, the other 2x restart postfix And MailScanner. I also changed the CRON times. The orphaned files in Milter Outbound now match the new CRON times.

I am using the commands
systemctl stop postfix
systemctl stop mailscanner

I WAS running the command to stop MailScanner twice to verify the service shuts down. I have changed that to 1x time in case the 2nd stop command was forcing MailScanner to quit before it finished its business.

The problem with the orphaned files continues on all 3 boxes, albeit less. This leads me to think it has to do with restarting Postfix and not just MailScanner. or the interaction between MailScanner and Postfix may contribute.

Sorry I am not more knowledgeable about this. My Linux skill are rather meager.

I will append to my script a copy command to move files from /milterout to /milterin.
