NethServer Version: 7.6.1810
Module: nethserver-mail 2.4.3-1
I’m having problem sending messages to a specific host, most of mails sent report this specific error, while trying to fix the problem, I found this post which says that to fix this you have to increase this three parameters
smtp_data_init_timeout
smtp_data_xfer_timeout
smtp_data_init_timeout
So I create a new custom template with:
# nano /etc/e-smith/templates-custom/etc/postfix/main.cf/91timeout
And put it this in it:
smtp_data_init_timeout = 600
smtp_data_xfer_timeout = 600
smtp_data_init_timeout = 600
Then did:
expand-template /etc/postfix/main.cf
systemctl restart postfix
Went to [ MailQueue ] -> [ Attempt to send ], however it didn’t worked, as again after approximately 3 min of sending a 5MB message postfix send the error “lost connection with [host] while sending message body”
Any help?
