I have configured Postfix on my Ubuntu server to send/receive mails.
While the sending works perfectly fine but the receiving doesn't. I want to forward all received mail to my gmail account.
My /etc/postfix/mail.cf is as follow:
# 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 $mail_name (Ubuntu)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = no
# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${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.
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = mail.compzzz.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
virtual_alias_domains = compzzz.com
virtual_alias_maps = hash:/etc/postfix/virtual
myorigin = /etc/mailname
mydestination = droplet1.compzzz.com, localhost.compzzz.com, localhost, compzzz.com, mail.compzzz.com
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all
And my /etc/postfix/virtual is:
@compzzz.com [email protected]
Any mail I send to [email protected], I receive a delivery failed email with unknown user error.
Am I going wrong somewhere?
Didn't get much help for this query, unfortunately. Therefore, I went through the postfix documentation and found the problem finally.
Just commenting the line which declared mydestination made it work.
i.e, replace the line
mydestination = droplet1.compzzz.com, localhost.compzzz.com, localhost, compzzz.com, mail.compzzz.com
with
#mydestination = droplet1.compzzz.com, localhost.compzzz.com, localhost, compzzz.com, mail.compzzz.com
For forwarding emails to another address (other than your server), mydestination parameter isn't required, only virtual_alias_domains and virtual_alias_maps are required.
