Outgoing Deferred Mail

[cehau37]

Hi,

At the moment we have quite a few amount of outgoing emails in the deferred queue due to connection timeout with the receiving mail server.

Is there a way to set a limit, lets say 24hours, for those deferred outgoing emails to stay in the queue before being purged?

Please advise.

Best Regards,

H

The default for deferred mails being purged is 5 days.
This is controlled by the postfix setting for 'maximal_queue_lifetime' - see `man 5 postconf`

If you want to reduce this - keep in mind that this limit is also used for downstream delivery - so if your downstream server is offline for more than 24h you will lose mail

I would suggest to keep the setting at its default - if you want to remove some particular mails you can do so with `postsuper` (see its manpage)

if you really want to adapt the postfix config setting you need to use the templateing system:

Hi Stoiko,

I ran "pmgconfig dump" to find the setting to put in the template file, but could not find anything related to "maximal_queue_lifetime" like you mentioned. Can you perhaps advise?

Cheers,

`pmgconfig dump` just prints the variables that PMG uses in various places of the templates:

https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmgconfig_template_engine

* since PMG does not expose queue_lifetime (and most other postfix options) in the API or GUI there is no variable for this.
* you still can (and need to for this) adapt the main.cf.in template - you just hardcode the desired value (e.g. 10d for 10 days instead of 5)...

I hope this explains it!
