Per <https://www.postfix.org/DEBUG_README.html#mail> post (this time in plain text rather than HTML form!) your server's configuration settings: $ postconf -nf $ postconf -Mf being sure to not rewrap line breaks. Attach the output as a text file if that's the easiest way to preserve whitespace. 2. At what stage in the email transaction is the timeout occuring? Post the specific log entries related to the transmission of one or a few messages that time out. > I would like to see the SMTP session Postfix has with the receiving > e-mail server to see what is going wrong. If you add the remote IP address to debug_peer_list, the SMTP commands and responses received are be logged. If your syslog subsystem is not dropping messages, you'll find them in the log. > I have tried to use the 'debug_peer_list' parameter with the domain of > the e-mail address I am trying to send e-mail to, but nothing more > shows in the mail log. The "debug_peer_list" setting takes a list of remote SMTP server (MX host) IP addresses or hostnames, which is not the same as the remote domain. > I can't tap into the connection to view the session from outside > Postfix because the connection is encrypted.
