Force queue delivery

[arstacey]

We are using version 2.6 with Exchange 2010. Periodically, we will have an issue with out Exchange server where messages will be rejected and a reply of "452 4.3.1 Insufficient system resources (in
reply to MAIL FROM command" sent back to proxmox. All incoming messages will be in a queued/deferred state. Once I reboot the Exchange server, messages will start being delivered again. But sometimes it takes 20-30 minutes for proxmox to retry delivery. Is there a way for me to force it to retry delivery on all queued mail?

Also, if I reboot proxmox while all this mail is in the queue, will it still be there waiting when it comes back up or does it drop the messages?

Thanks!

first, you should find the cause of the insufficient resources and fix it.

you can flush the queue, just go to "Administration/Queues" and click on the red arrow (near Mail Queue) and select "Flush Queue"

 

[arstacey]

Thanks. To be clear, will Flush Queue try to deliver the mail or just empty the queue?

 

[tom]

yes, this will just force delivery.

if you choose "delete all messages" you will loose the messages, but this sounds clear.

This is greylisting. This is just a temporary reject, and is not really a problem. If you are concerned about delays, you can turn off greylisting at Configuration/MailProxy/Options/Greylisting

Yes, I see you are still blocking Deferred, I am 3 days without sending email on port 26

Oh sorry - I was wrong. Seems the filter daemon is not running (pmg-smtp-filter). Please check and restart that service if not running.

Hello

Yes it's running, I'm still having problems

 

[dietmar]

Any hints in /var/log/syslog? How much RAM does that machine have?
