Hello, i am trying to extend the max size of a mail. Usually the default email size limit is set in main.cf of postfix. message_size_limit=putnumberofbyteshere As it seems like there is no impact if i change only the message_size_limit . Does this work with ISPconfig 3 as well or do i need to change other values as well, e.g. maxium attachment size of the mailscanner or is it possible to set this value for each user ? . System: Debian 6 Postfix 2.7.1 Cheers Sisko
