relay denied
 
I'm trying to use thunderbird to send email from an external location. Receiving email works perfectly via IMAp.
For the SMTP server settings I'm using the server via port:25, and have Security and Authentication, Use name and password checked... using the user's name as his email address. I have TLS, if available enabled as well.

/var/log/mail.info:
Code:

554 5.7.1 <user@hisdomain.com>: Relay access denied; from=<me@mydomain.ca> to=<user@hisdomain.com> proto=SMTP helo=<[192.168.1.133]>
snipet from main.cf
Code:

relayhost =
smtpd_sasl_authenticated_header = yes
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf, reject_unauth_destination
smtpd_tls_security_level = may
transport_maps = proxy:mysql:/etc/postfix/mysql-virtual_transports.cf
relay_domains = mysql:/etc/postfix/mysql-virtual_relaydomains.cf

maildrop snipet from master.cf:
Code:

maildrop  unix  -      n      n      -      -      pipe
  flags=R user=vmail argv=/usr/bin/maildrop -d vmail ${extension} ${recipient} ${user} ${nexthop} ${sender}

Used the perfect server ubuntu 9.04 + ISPconfig3 as my guide.

Thanks much,
MM

Your mail client did not authenticate itself with smtp-auth. Please enable smtp authentication in the email client.

Using Thunderbird I've tried all 4 authentication options...

Security and Authentication
Use name and password is enabled. (using email address as user)
Use secure connection has 4 options and I've tried all 4.
No
TLS if available
TLS
SSL

TLS option gives "Unable to connect to SMTP server myserver via STARTTLS since it doesn't support EHLO.

using TLS if available or NO gives the relay error I quoted above.

Please post all messages that appear in the mail log when you try to send a meial. There must be more lines then just the line you posted.

From /var/log/mail.log:
Code:

Jul 21 08:47:42 dbl postfix/smtpd[25947]: NOQUEUE: reject: RCPT from externalserver.domain.com[x.x.x.x]: 554 5.7.1 <user@hisdomain.com>: Relay access denied; from=<me@mydomain.ca> to=<user@hisdomain.com> proto=SMTP helo=<[192.168.1.133]>

where externalserver.domain.com is the remote location I'm currently at.

I'm using "use name and password" authentication with the secure connection option of "TLS, if available"

Thanks for the help. Really appreciate it.

Any other insight into why sending from an external location might be failing? There's really not much more in the log files.

Is there a table in MySQL I could check for the right relay authentication information?... or a config file on my Ubuntu 9.04 server?

A test I could try locally on the machine?

Thanks for having a look. Appreciate it.

Ok i came up with few things so try it out:

first try making in master.cf like this:

smtp inet n - n - - smtpd

and try if it is working, after that try setting:

smtps inet n - n - - smtpd

and try again

after try like this:

open up main.cf and go throu following

smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_sasl_local_domain = $myhostname - you defined this right?
broken_sasl_auth_clients = yes

at the type in console postconf and check if these match:

smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf, reject_unauth_destination
smtpd_reject_unlisted_recipient = yes
smtpd_reject_unlisted_sender = no
smtpd_restriction_classes =
smtpd_sasl_auth_enable = yes
smtpd_sasl_authenticated_header = yes
smtpd_sasl_exceptions_networks =
smtpd_sasl_local_domain =
smtpd_sasl_path = smtpd
smtpd_sasl_security_options = noanonymous
smtpd_sasl_tls_security_options = $smtpd_sasl_security_options
smtpd_sasl_type = cyrus
smtpd_sender_login_maps =
smtpd_sender_restrictions = check_sender_access mysql:/etc/postfix/mysql-virtual_sender.cf

lets see if it worked out :)

madmerlin 23rd July 2009 19:19

unfortunately those changes in the master.cf file didn't help.

I also made sure all my settings matched the ones you listed with postconf.

Frustrating. Thanks for the help appreciate it. Any other ideas?
