Problem with Distribution List

[nmsalert10]

We had a Distribution List consisting of 1000+ users on 6.0.10 version. The same DL gives errors when we try to send mail to it. We tried to delete and create the DL but to no use.Still the same issue. What could be the problem?

Below is the error:

Hello,
I'm not sure if it is the only problem you're facing, but distribution list size is limited to 1000 recipients by default. You can increase it by changing virtual_alias_expansion_limit postfix variable.

Hello Jiri,

Where exactly this variable to be set. I mean what is the path location for this variable.

[Jorgeos]

Hello,
find your current settings via this command:
$ postconf virtual_alias_expansion_limit

set new value like this:
$ postconf -e virtual_alias_expansion_limit=[count]
(ie. postconf -e virtual_alias_expansion_limit=1234 )

and restart postfix after the change:
$ zmmtactl restart
(all commands run as zimbra user)

Regards,
Jiri
