Description Tobias Birkefeld univentionstaff 2015-01-29 14:15:30 CET 
In larger mail environments check for spam could delay the mail processes. It would be nice to configure the maximum amaivs processes. You have to edit two template files:

/etc/univention/templates/files/etc/amavis/conf.d/60-univention

the important variable is:
$max_servers  =  2

In order to:
# You may want $max_servers to match the width of your MTA pipe
# feeding amavisd, e.g. with Postfix the 'Max procs' field in the
# master.cf file, like the '2' in the:  smtp-amavis unix - - n - 2 smtp

you also have to set the number in the postfix master.cf template:

/etc/univention/templates/files/etc/postfix/master.cf.d/30_antivir

smtp-amavis unix -      -       n     -       2  smtp

Comment 2 Daniel Tröder univentionstaff 2015-07-17 12:06:31 CEST 
Commits 62191 - 62193 add a new UCRV mail/antivir/max_servers to configure the max. number of concurrent Amavis processes. When unset "2" is used, not changing the current default.

YAML commit 62195:
* 2015-07-17-univention-mail-postfix.yaml
* 2015-07-17-univention-antivir-mail.yaml
