Postfix/Courier SMTP Problem

Problem Solved!

I'm running Ubuntu 10.04, and I'm trying to set up Postfix and Courier as a mailserver. I am able to connect to a POP account under Courier with no problems. I followed the postfix/courier tutorial on the linode library, and I am using mySQL for everything. My website is www.benstevinson.com. I'm trying to get the email address ben@benstevinson.com to work, and I cannot. I have no troubles receiving mail that is sent to ben@benstevinson.com, and can access that email address through POP through Apple Mail or Thunderbird. I cannot connect to my SMTP server to send out mail with an external client. It says that my server (and lists it as mail.benstevinson.com) times out. I am not quite sure what to do here. My FQDN is trinity.benstevinson.com, and I can use mailx to send out to another place, but it says my email address is ben@trinity.benstevinson.com. I am trying to change that.

I just ran a tail -50 /etc/postfix/mail.log and got this:

I looked at this and noticed that saslauthd was not started, so I started it. Then it just timed out when I tried to use Thunderbird to send an email. I can still receive mail, however.

I am putting my account as ben@benstevinson.com in my server configurations, and benstevinson.com as my server.

Here is my /etc/aliases file:

# See man 5 aliases for format
postmaster:    root@benstevinson.com
ben:            ben@benstevinson.com

And 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 = /usr/share/doc/postfix

# TLS parameters
smtpd_tls_cert_file = /etc/postfix/smtpd.cert
smtpd_tls_key_file = /etc/postfix/smtpd.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 = benstevinson.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = benstevinson.com, localhost.benstevinson.com
relayhost =

virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf
virtual_mailbox_base = /home/vmail
virtual_uid_maps = static:5000
virtual_gid_maps = static:5000
smtpd_sasl_auth_enable = yes
broken_sasl_auth_clients = yes
smtpd_sasl_authenticated_header = yes
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination

proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $virtual_mailbox_limit_maps

What do I have wrong here? I cannot figure it out.

Thanks in advance!

Are you sure your ISP is not firewalling your smtp port?

Try the above telnet command from your external host, and also try it from your server.

@Captain Briney:

My FQDN is trinity.benstevinson.com, and I can use mailx to send out to another place, but it says my email address is ben@trinity.benstevinson.com. I am trying to change that.
This is controlled by the "myorigin" line in your main.cf.

If you want the locally generated mail to come from whoever@benstevinson.com, then you can just comment out the myorigin line and it will default to $myhostname.

Okay, I've changed my "myorigin" file to be benstevinson.com instead.

I'm at home now, I was at work when I generated those logs.

Trying it from both my PC and my Server results in the exact same telnet message that you posted, yet I still cannot connect.

Here's another log file. It still says login incorrect and asks for my password which it will then reject:

Okay, I've done a bit more. I commented out myorigin, and going back over the postfix guide, I noticed I didn't add run adduser postfix sasl, so I did. I restarted everything, and I'm still having the same problem. I cannot connect to my SMTP server. Also, thunderbird says that my SMTP server is not encrypted, which confuses me, because I believe that it should be if this was working correctly.

When I sent a mail out using mailx it shows up as ben@benstevinson.com, now I'm just trying to figure out SMTP. I'm going to retrace my steps and see if I messed up somewhere.

Okay I'm just using Google Apps instead, screw Postfix. Thanks for the help :)
