Hello; I follwed Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Debian Lenny) and I can send receive emails using SquirrelMail no problem but I when using remote client I can receive but not send. I did check the option to use authentication same as for the pop. I have tried many things and searched the forum for hours and no luck. Hope someone can help me with this. Thanks!!! my mail.log Code: Apr 2 15:49:53 Email1 postfix/smtpd[17128]: connect from unknown[xx.xx.xx.xx] Apr 2 15:49:53 Email1 postfix/smtpd[17128]: lost connection after UNKNOWN from unknown[xx.xx.xx.xx] Apr 2 18:52:53 Email1 postfix/smtpd[17313]: NOQUEUE: reject: RCPT from unknown[xx.xx.xx.xx]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=SMTP helo=<[xx.xx.xx.xx]> Apr 2 18:52:58 Email1 postfix/smtpd[17313]: disconnect from unknown[xx.xx.xx.xx] my /sasl/smtpd.conf Code: pwcheck_method: saslauthd mech_list: plain login allow_plaintext: true auxprop_plugin: mysql sql_hostnames: 127.0.0.1 sql_user: mail_admin sql_passwd: ***** sql_database: mail sql_select: select password from users where email = '%u' postconf -n Code: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no broken_sasl_auth_clients = yes config_directory = /etc/postfix content_filter = amavis:[127.0.0.1]:10024 html_directory = /usr/share/doc/postfix/html inet_interfaces = all mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 message_size_limit = 30720000 mydestination = FQDN, localhost, localhost.localdomain myhostname = FQDN mynetworks = 127.0.0.0/8 myorigin = /etc/mailname 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 $virtual_mailbox_limit_maps readme_directory = /usr/share/doc/postfix receive_override_options = no_address_mappings recipient_delimiter = + relayhost = smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = yes smtpd_tls_cert_file = /etc/postfix/smtpd.cert smtpd_tls_key_file = /etc/postfix/smtpd.key smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_use_tls = yes transport_maps = proxy:mysql:/etc/postfix/mysql-virtual_transports.cf virtual_alias_domains = virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, mysql:/etc/postfix/mysql-virtual_email2email.cf virtual_gid_maps = static:5000 virtual_mailbox_base = /home/vmail virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf virtual_mailbox_limit_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailbox_limit_maps.cf virtual_mailbox_limit_override = yes virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf virtual_maildir_extended = yes virtual_maildir_limit_message = "The user you are trying to reach is over quota." virtual_overquota_bounce = yes virtual_uid_maps = static:5000 saslauthd Code: # # Settings for saslauthd daemon # Please read /usr/share/doc/sasl2-bin/README.Debian for details. # # Should saslauthd run automatically on startup?

Please double-check that you've enabled "Server requires authentication" in your email client. Are there any other errors in the mail log?
Hi Falco; Thanks for the reply... That was the first thing I checked to make sure it was checked. Does the encryption have to be SSL or TLS I chose none. As for the logs there is more but nothing relevant just the ones for Squirrelmail that does work, and the pop3 authenications that work too. Thanks again, Kurt
Please use no encryption in your email client. If it still doesn't work, please compare your setup with the one from the tutorial. Maybe you made a typo somewhere.
Hi Falco; Thanks again for your reply. Which files are the ones that would cause this? The only thing that does not work is sending out using a email client. When I use squirrelmail it works perfectly. Could this be caused by amavis? Thanks again, Kurt
No I was never able to resolve this... Checked the main.cf saslauth multiple times checked all the files but still nothing. I'm totally clueless, and don;t know where else to look... Thanks!!!
I did some more tests today and I realized that I can send emails with outlook if i'm on the same network as the server. The port is definately open from ouside. mail.log if send from workstation on the local network Code: May 5 14:44:07 Email1 postfix/smtpd[13817]: connect from unknown[192.168.x.x] May 5 14:44:07 Email1 postfix/smtpd[13817]: C8D10BC27C: client=unknown[192.168.x.x], sasl_method=LOGIN, [email protected] May 5 14:44:07 Email1 postfix/cleanup[13825]: C8D10BC27C: message-id=<000001c9cdb1$c37c2b90$4a7482b0$@com> May 5 14:44:07 Email1 postfix/qmgr[28318]: C8D10BC27C: from=<[email protected]>, size=2588, nrcpt=1 (queue active) May 5 14:44:10 Email1 postfix/smtpd[13817]: disconnect from unknown[192.168.x.x] May 5 14:44:16 Email1 postfix/smtpd[13835]: connect from localhost[127.0.0.1] May 5 14:44:16 Email1 postfix/smtpd[13835]: 5DC75BC27D: client=localhost[127.0.0.1] May 5 14:44:16 Email1 postfix/cleanup[13825]: 5DC75BC27D: message-id=<000001c9cdb1$c37c2b90$4a7482b0$@com> May 5 14:44:16 Email1 postfix/qmgr[28318]: 5DC75BC27D: from=<[email protected]>, size=3049, nrcpt=1 (queue active) May 5 14:44:16 Email1 postfix/smtpd[13835]: disconnect from localhost[127.0.0.1] May 5 14:44:16 Email1 amavis[29561]: (29561-17) Passed CLEAN, LOCAL [192.168.x.x] [192.168.x.x] <[email protected]> -> <[email protected]>, Message-ID: <000001c9cdb1$c37c2b90$4a7482b0$@com>, mail_id: 87VhK01b8s8Y, Hits: 0.847, size: 2588, queued_as: 5DC75BC27D, 8470 ms May 5 14:44:16 Email1 postfix/smtp[13826]: C8D10BC27C: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=8.7, delays=0.2/0.02/0.02/8.5, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=29561-17, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 5DC75BC27D) May 5 14:44:16 Email1 postfix/qmgr[28318]: C8D10BC27C: removed May 5 14:44:16 Email1 postfix/smtp[13838]: 5DC75BC27D: enabling PIX workarounds: disable_esmtp delay_dotcrlf for mail.receiver.com[xx.xx.xx.xx]:25 May 5 14:44:17 Email1 postfix/smtp[13838]: 5DC75BC27D: to=<[email protected]>, relay=mail.receiver.com[xx.xx.xx.xx]:25, delay=1.2, delays=0.06/0.08/0.55/0.48, dsn=2.6.0, status=sent (250 2.6.0 <000001c9cdb1$c37c2b90$4a7482b0$@com> Queued mail for delivery) May 5 14:44:17 Email1 postfix/qmgr[28318]: 5DC75BC27D: removed mail.log if send from outside Code: May 5 17:33:04 Email1 postfix/smtpd[14423]: connect from unknown[xx.xx.xx.xx] May 5 17:33:05 Email1 postfix/smtpd[14423]: lost connection after UNKNOWN from unknown[xx.xx.xx.xx] May 5 17:33:05 Email1 postfix/smtpd[14423]: disconnect from unknown[xx.xx.xx.xx] I'm thinking it has to do with the spamassasin or something similar. Any help is greatly appreceated...
Hi Falco; You think it's firewall? But then it would be firewall on the linux... since the logs are registering a connection attempt but do not allow it. And if it's the firewall on the system why would the mail.log register this? Any tips on how I can trouble shoot this? Thanks again!!
Fixed!!! Hi Falco; You were correct!!! It was the firewall... I had a Cisco PIX with PIX MailGuard "fixup protocol smtp" enabled. This was the problem all a long. I disabled this option and everything is working great!! Thanks again!! Kurt
