Hi Zhang,

I'm confused about the information at https://docs.iredmail.org/change.mail.a … .size.html . At the top it states, "To change mail attachment size, we have to change 3 settings." It then explains a setting in /etc/postfix/main.cf. Currently I have set that to the default of 15 MB. In the "Change message size limit in postfix" section it has a note about Dovecot, but no instructions on what needs to be changed in its configuration. I don't see an obvious reference in /etc/dovecot/dovecot.conf that refers to "size" or "limit".

Back to the "3 settings"; there are six headings related to Postfix, Roundcube (and 2 headings under that), Nginx, SoGo and Outlook. Is the "3 settings" old text that just needs to be updated, and refers to that list, or are some instructions missing?

Lastly, do I understand correctly from https://forum.iredmail.org/topic12842-d … -size.html that "message_size_limit" in main.cf overrides anything set in iRedAdmin-Pro at Domains & Accounts -> DOMAIN -> Throttling? In other words, if the limit set in iRedAdmin-Pro is higher than the limit in main.cf, it will have no effect?

Thanks.

Craig
