I am running Ubuntu 8.10 and trying to set up Postfix to relay all email to my Gmail account. I can't seem to be able to get the relay to work properly for some reason and I would really appreciate it if someone could point me in the right direction.

When I send an email to my email address, I get an “Undelivered Mail Returned to Sender” error email with the following error: “relay access denied (in reply to RCPT TO command)” or “Relay access denied (state 14).”

In mail.log I see errors like this one:

NOQUEUE: reject: RCPT from mail.domain.com[###.###.###.###]: 554 5.7.1 : Relay access denied; from=<username@domain.com> to=<username=domain.com> proto=ESMTP helo=<mail.domain.com>

Here is my main.cf file:

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.

myhostname = li53-52.members.linode.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = li53-52.members.linode.com, localhost.members.linode.com, , localhost
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all

# Gmail
relayhost = [smtp.gmail.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_tls_CAfile = /etc/postfix/cacert.pem
smtp_use_tls = yes

Here is my sasl_passwd:

[smtp.gmail.com]:587 username@gmail.com:password

Any suggestions?

After messing around with things a bunch, I think I have my problem solved. I was trying to forward all email sent to addresses at my domain name to my gmail account and I realized that I was going about things in the wrong way.

Here's my solution:

in main.cf, I restored to the original main.cf file and added these two lines:

virtual_alias_domains = domain.com
virtual_alias_maps = hash:/etc/postfix/virtual

Then I created /etc/postfix/virtual and put this in there:

#/etc/postfix/virtual
user@domain.com user@gmail.com
@domain.com user

Then I ran

postmap /etc/postfix/virtual

And in my user home directory, I created a file called ".forward" and placed this in it

user@gmail.com

Everything seems to be working perfectly (all mail sent to *@domain.com is being forwarded to user@gmail.com).

If your postfix mail is working properly, you could just put a .forward
file in your mailbox.

Here is the other way I know of. I use gmail for one of my domains and
I simply have the gmail mx records in my nameserver. Google tells you
how to do this. Something like:

yourdomain.com. IN MX 1 ASPMX.L.GOOGLE.COM.
yourdomain.com. IN MX 5 ALT1.ASPMX.L.GOOGLE.COM.

Hope this gives you some ideas.

Thanks for the response. Is that for Google Apps for your domain? I'm not interested in using that--I'd just like to forward emails sent to *@mydomain.com to username@gmail.com
