I have a Centos 6 setup running a web and mail server. Email server works fine, however, my clients cannot send or receive emails with attachments size greater than 10MB.
I tried setting
/etc/postfix/main.cf with no luck:
mailbox_size_limit = 1073741824 message_size_limit = 52428800
I searched on how to change mail size limit for amavisd-new and spamassassin, but couldn't find a working solution. How can I change the size limit for all the mails (body+attachments)? Also I can't see those rejects inside log files like
/var/log/maillog. Is there any other log files I should be looking to check for mail rejects?
dovecot, IMAP and POP3 server, be related to this issue?
