Description
When postfix encounters a resource problem, the postmaster receives a mail notification of the problem with a transcript of the session but without useful information to debug the problem.
The maillog contains useful information.
I'd like to avoid mail notifications.
I added a custom template:
$ cat /etc/e-smith/templates-custom/etc/postfix/main.cf/85notify_classes # disable resouce problems notifications to postmaster notify_classes = software
Associated revisions
main.cf template: silence postfix resource problems notifications. Refs #2824
- Increased default smtpd_proxy_timeout to 240 seconds
- Restricted notify_classes = software
main.cf: Silence postfix resource/software problems notifications. Refs #2824
Never send notifications to postmaster. Administrator is expected to
read the maillog.
History
#1 Updated by Filippo Carletti about 7 years ago
Resource problems are usually found in amavis mail processing.
To avoid smtp sessions errors, we could use:
smtpd_proxy_timeout = 240s
Edit: by default smtpd_proxy_timeout = 100

Test case
Don't know how to reproduce "when postfix encounters a resource problem"...
The modified version differs from nethserver-mail-common
v1.3.3 only in the two given parameters, changed from Postfix default values. It could be tested on a production environment.

Proposed solution doesn't suppress notifications.
New proposed solution is to set the following options:
notify_classes = smtpd_proxy_timeout = 240s
The first option will suppress all mail notifications, the second one relaxes the timeout when amavis doesn't quickly respond to requests.
I suggest to test the proposed solution on a running machine.
