Postfix conf problem, almost got it... :)

mewhocorrupts · 02-04-2008, 05:08 PM

So I've been at this thing for a bit now, and I have it down to a single issue (which may or may not be a combination of multiple problems). I can send/receive from within my own domain, and send to external domains, all without problems. The only complication remaining is when I try to send email to my domain from an external address. I have tried from a Yahoo, Hotmail, and corporate account, all to no avail.

Here is my postconf -n:

Code:

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
home_mailbox = Maildir/
mailbox_size_limit = 0
mydestination = MyDomain.com, localhost, localhost.$myorigin, mail.MyDomain.com
mydomain = MyDomain.com
myhostname = indie
mynetworks_style = host
myorigin = $mydomain
recipient_delimiter = +
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
smtpd_helo_required = yes
smtpd_recipient_restrictions = permit_mynetworks
smtpd_sasl_auth_enable = yes
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache

I'm sure a portion of it is incorrect, but for all of my trying, I am yet to produce a reason why it won't receive mail. I removed SpamAssassin, and check to make sure that the SMTP ports weren't being blocked. I've also contacted my provider, and checked to ensure that nothing on their end was preventing mail from coming through.

Any ideas? I'll try just about anything at this point.

Thanks much,

Kit

I just setup Postfix on Debian 4.0 directly on my home ISP LAN (RoadRunner) and it works perfect!

Here is what I have:

Code:

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
home_mailbox = Maildir/
inet_interfaces = all
mailbox_size_limit = 0
mydestination = carlwill.com, swordfish.carlwill.com, localhost.carlwill.com, localhost
myhostname = swordfish.carlwill.com
mynetworks = 192.168.1.0/24, 192.168.2.0, 127.0.0.0/8
myorigin = carlwill.com
recipient_delimiter = +
relay_domains = carlwill.com
relayhost = 
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Linux)
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtpd_use_tls = yes

Can you post the relevant section of your log when you attempt to receive a message?

/var/log/mail.err mail.info

There are thousands of lines of the following:

Code:

Feb  4 10:37:15 indie postfix/smtpd[15689]: fatal: parameter "smtpd_recipient_restrictions": specify at least one working instance of: check_relay_domains, reject_unauth_destination, reject, defer or defer_if_permit
Feb  4 10:38:16 indie postfix/smtpd[15912]: fatal: parameter "smtpd_recipient_restrictions": specify at least one working instance of: check_relay_domains, reject_unauth_destination, reject, defer or defer_if_permit
Feb  4 10:39:17 indie postfix/smtpd[16232]: fatal: parameter "smtpd_recipient_restrictions": specify at least one working instance of: check_relay_domains, reject_unauth_destination, reject, defer or defer_if_permit

I checked that field -- smtpd_recipient_restrictions -- and added one of the referenced filters.

Edit: Well... that was anticlimactic. I added "check_relay_domains" to the filter, and behold, it worked fine. Why does it require a denial filter, when permit_mynetworks was already present?

To prevent becoming an open relay.
