Hello I have a mail server where I use TPS FC4 with ISPConfig. The system is stable and works great. But I seem to have some trouble with sending large e-mails. I have set message size in postfix main.conf to 81920000. Restarted postfix, and run "postconf | grep size" witch returns: Code: berkeley_db_create_buffer_size = 16777216 berkeley_db_read_buffer_size = 131072 body_checks_size_limit = 51200 bounce_size_limit = 50000 header_size_limit = 102400 mailbox_size_limit = 51200000 message_size_limit = 81920000 But I still can`t seem to be able to send larger e-mails than around 40MB. And is the message size limit in postfix also the limit for incoming mail. What about sending/receiving time-out, any point in changing this, and where to do it?
It'S for incoming emails only. Do you get any errors when sending large emails, or delivery status notification emails? Any errors in your mail log?
