I’ve just finished struggling through email setup on Ubuntu 14.04. TekSavvy apparently blocks port 25 outbound, except to their own mail servers. If you call and ask nicely, they will tell you it costs $4/month to unblock port 25 to the rest of the internet (you must pay for a Static IP in order to obtain unrestricted internet).
But there is an alternative!
Fortunately TekSavvy’s mail servers can be used to relay your outbound mail. This should be easy to set up, but I was plagued with a 530 Authentication required (in reply to MAIL FROM command) error when trying to use out.teksavvy.com:1025 (the server that was recommended to me).
The solution was to use smtp.teksavvy.com:25 – the SASL options are likely now unnecessary in my conf file, but since it works I’ve decided to leave things as-is.
In case it helps someone, here’s my Postfix configuration:
root@SERVER:/home/jordan# postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no config_directory = /etc/postfix inet_interfaces = all inet_protocols = ipv4 mailbox_size_limit = 0 mydestination = localhost myhostname = SERVER mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 myorigin = /etc/mailname readme_directory = no recipient_delimiter = + relayhost = smtp.teksavvy.com:25 smtp_always_send_ehlo = yes smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/saslpasswd smtp_sasl_security_options = smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtp_use_tls = yes smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_use_tls = yes
Does that not turn your system into an “open relay” though?
Thanks so much. I was trying to get outbound SMTP to work for days!
i’m using teksavvy as an isp also and trying to send mail out.
for /etc/postfix/saslpasswd, is it in the format:
smtp.teksavvy.com USERNAME:PASSWORD
if so, how do we get our teksavvy username and password?
Hi, thanks for the guide, this worked for me, also on Teksavvy – wondering if you also had to enable anything similar for inbound mail?
