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:
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?
