Good morning all
I've configured postfix on my linux server. For the most part, I got everything working (IMAP, apache, etc) but for some reason, I can't get postfix to work remotely.
Postfix works locally to send mail. E.g. when I telnet locally to port 25. However, when I try to telnet from outside, the connection closes almost immediately.
I've looked at
various configuration options and
tuning enhancements but found nothing helpful.
Here is my config:
Code:
main.cf:
#See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) [hostname redacted]
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = no
# TLS parameters
# smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
# smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key

smtpd_tls_key_file=/etc/certs/server.private.openssl.key
#smtpd_use_tls=yes
smtpd_tls_security_level=may
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.
