Hi =) I used the awesome tut Falco's put up at: http://www.howtoforge.com/virtual_users_and_domains_with_postfix_debian_etch I'm getting a couple of weird errors I cant' seem to track down using this tutorial. The host is on Xen (it's a DomU), if that makes a difference. For some reason my forwarding stopped. It was working just fine, but it seems to have died about a week ago and I've been trying to troubleshoot it since. Here are some clips from the logs: (i replaced the actual domain with *domain.tld* for this forum) mail postfix/smtp[2538]: fatal: valid hostname or network address required in server description: *domain.tld* I get that ALOT... (thousands in mail.log) also: postfix/qmgr[1438]: warning: mail for [127.0.0.1]:10024 is using up 19997 of 20000 active queue entries Jul 10 23:54:43 mail postfix/qmgr[1438]: warning: you may need to reduce amavis connect and helo timeouts Jul 10 23:54:43 mail postfix/qmgr[1438]: warning: so that Postfix quickly skips unavailable hosts Jul 10 23:54:43 mail postfix/qmgr[1438]: warning: you may need to increase the main.cf minimal_backoff_time and maximal_backoff_time Jul 10 23:54:43 mail postfix/qmgr[1438]: warning: so that Postfix wastes less time on undeliverable mail Jul 10 23:54:43 mail postfix/qmgr[1438]: warning: you may need to increase the master.cf amavis process limit Jul 10 23:54:43 mail postfix/qmgr[1438]: warning: please avoid flushing the whole queue when you have Jul 10 23:54:43 mail postfix/qmgr[1438]: warning: lots of deferred mail, that is bad for performance Jul 10 23:54:43 mail postfix/qmgr[1438]: warning: to turn off these warnings specify: qmgr_clog_warn_time = 0 Ok, so they tried to send out a mass mailer and it filled the queue... anyway I can empty that without loosing the mail? And this may be of interest... It's hard to catch unique errors in the logs because they clog up so fast, but I notice this: Jul 10 23:40:59 mail postfix/master[1432]: warning: /usr/lib/postfix/smtp: bad command startup -- throttling The client using this server is hosting 2 domains on it and forwarding them. (if that helps) I'm sure I've missed something really silly and trivial here... Any suggestions are much appreciated =) Thanks!
What are the outputs of Code: postfix check and Code: postconf -n ? Can you check if your domain can be resolved: Code: dig domain.tld
Hey Falco, thanks for the reply mail:/var/log# postfix check mail:/var/log# I suppose that means the check was ok? I should have posted the postconf -n earlier, my bad... here we go: mail:/var/log# postconf -n 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 inet_interfaces = all mailbox_size_limit = 0 mydestination = mail.domain1.com, mail.domain2.com, localhost, localhost.localdomain myhostname = mail.domain1.com 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 receive_override_options = no_address_mappings recipient_delimiter = + relayhost = 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_tls_cert_file = /etc/postfix/smtpd.cert smtpd_tls_key_file = /etc/postfix/smtpd.key smtpd_tls_loglevel = 1 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_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf virtual_uid_maps = static:5000 the dig definately goes where it should, i've got both A and PTR records working just splendidly. I should note that the server has 2 ip's and 2 domains pointed to each IP, and A and PTR records for each working just fine. Also, I edited the post, but I can't seem to connect via POP from outside, however I can telnet to the pop port from localhost as the tutorial advises to check if the pop server is responding: mail:/var/log# telnet localhost pop3 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Hello there. quit +OK Better luck next time. Connection closed by foreign host. and mail:/var/log# telnet localhost 25 Trying 127.0.0.1...

Do you host the server at home or in your office? If so, you should ask your provider if they block port 25.
It's totally not port 25 bring blocked. I'm doing it from the office, we're an ISP and I'm the sysadmin who controls the firewall =) The crux of the issue, i think, falls in the following errors: # tail mail.warn Jul 12 15:14:50 mail postfix/smtp[19440]: fatal: valid hostname or network address required in server description: mail.domain1.com Jul 12 15:14:51 mail postfix/master[20465]: warning: process /usr/lib/postfix/smtp pid 19440 exit status 1 Jul 12 15:14:51 mail postfix/master[20465]: warning: /usr/lib/postfix/smtp: bad command startup -- throttling Jul 12 15:14:51 mail postfix/qmgr[20470]: warning: private/smtp socket: malformed response Jul 12 15:14:51 mail postfix/qmgr[20470]: warning: transport smtp failure -- see a previous warning/fatal/panic logfile record for the problem description and from mail.log: Jul 12 15:15:53 mail postfix/error[19537]: 8A2B8173245: to=<*user*@domain2.com>, relay=none, delay=185543, delays=185543/0.05/0/0.04, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]: Connection refused) I can't seem to find much help on these issues when i search for 'fatal: valid hostname or network address required in server description'. The 2nd google option is this thread, actually =\
