Configuring maxmessagesize

Revision as of 20:18, 31 January 2007 by Dsga1 (talk | contribs) (Postfix configuration)

The following provides instructions how to enable a Maximum Message Size for messages passing through the Zimbra MTA (ie. Postfix). The "maxmessagesize" config is unique to each Zimbra MTA you have (ie. if you have a distributed Zimbra deployment, you'll need to make change in each MTA host where you want this maxmessagesize limit enforced).

Postfix configuration

The following commands will set the message_size_limit to 2MB, you can adjust this value to your needs:

su - zimbra

postconf -e message_size_limit=''  ; this will clear the current value

zmprov mcf zimbraMtaMaxMessageSize 2048

wait two minutes for the changes to be published then confirm the changes with this command:

postconf | grep message_size_limit
