Postfix mail is held in queue indefinitely...
 
I am running Debian 3.1 on a VMS From TekTonic Hosting.

I installed Postfix, SASL, Courier-IMAP(-SSL), MySQL from this howto: http://www.howtoforge.com/virtual_po..._quota_courier

Postfix 2.1.5

I have gotten the SMTP server authenticating, accepting mail from clients, delivering it to other email servers, but when the mail is destined for the local machine, it just sits in queue. Postfix is successfully chrooted and all authentication is working fine, I do not want to remove it from the chroot, so I cannot remove the proxy:mysql:... entries from the main.cf file. I cannot change those entries to just mysql:... because it breaks the SASL authentication (even when postfix has been removed from chroot mode in master.cf).

Here is a snapshot of my log - which starts with a test email from my personal domain to <username>@hidesato.com.
Code:

Jan 11 22:08:22 mail postfix/smtpd[7407]: connect from cpe-x-x-x-x.satx.res.rr.com[x.x.x.x]
Jan 11 22:08:22 mail postfix/smtpd[7407]: D62AD4832496: client=cpe-xxx-xxx-xxx-xxx.satx.res.rr.com[x.x.x.x], sasl_method=PLAIN, sasl_username=<username>@hidesato.com

Jan 11 22:08:23 mail postfix/smtpd[7407]: disconnect from cpe-x-x-x-x.satx.res.rr.com[x.x.x.x]
Jan 11 22:08:42 mail postfix/virtual[7798]: fatal: mysql:/etc/postfix/mysql-virtual_mailboxes.cf: proxy map is not allowed for security sensitive data
Jan 11 22:08:43 mail postfix/master[5830]: warning: process /usr/lib/postfix/virtual pid 7798 exit status 1
Jan 11 22:08:43 mail postfix/master[5830]: warning: /usr/lib/postfix/virtual: bad command startup -- throttling

My guess is that this is related to the delivery to Maildir under the username vmail, in order to get the IMAP client to connect to the server I had to manually do a maildirmake /home/vmail/<username>. After those directories existed, the IMAP client (thunderbird) connected just fine - but all my mail is stuck in queue.

Code:

mail:/usr/src# mailq
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------

I really would like to get the mail delivery working, thats the last thing to fix and I can get my email up and going on this new host. Any help would be appreciated. I followed the tutorial very closely, I did change all the references to 127.0.0.1 to localhost in the mysql files because for some reason the loopback ip address wasn't working. I can provide more information if needed of course.

Did you run this command, as described in the tutorial:
Code:

postconf -e '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's in /etc/hosts? Also post the output of
Code:

ifconfig

Is this a virtual server?

Anyway, after you've run the postconf command and restarted Postfix, has Postfix delivered the mails in the queue?

squallbsr 13th January 2006 00:21

Virtual Server
 
Yes, this is a virtual server, no the emails have not gone through.

falko 13th January 2006 03:25

What's in the mail log now?
Please post /etc/postfix/main.cf here.

squallbsr 13th January 2006 04:04

Here is the same thing repeated over and over in the mail log...

Code:

Jan 12 21:58:41 mail postfix/virtual[3077]: fatal: mysql:/etc/postfix/mysql-virtual_mailboxes.cf: proxy map is not allowed for security sensitive data

Here is main.cf

mail:~#

Keep in mind that mail works just fine when it goes to another server, the mail client will logonto smtp-tls (mail.hidesato.com) and send the email to the correct server (i.e. hotmail.com). I don't have refused connections, it just cannot deliver local mail. /me scratches head

falko 13th January 2006 23:58

Have you tried to remove all the proxy: strings in /etc/postfix/main.cf (restart Postfix afterwards)?

squallbsr 14th January 2006 06:10

Proxy removed doesn't help
 
I remove the proxy: from proxy:mysql:...

Mail still sits in queue. smtp is still chrooted, IMAP-SSL still works fine, SMTP to other mail servers works fine. For some reason it just cannot deliver the mail to one of the MailDir's under /home/vmail (i.e. /home/vmail/hidesato.com/<username>/ OR /home/vmail/mail.hidesato.com/test/)

I would imagine that the proxy items need to be there because of the chroot and not being able to read config from the /etc/postfix directory.

The postfix documentation is confusing because in places talking about virtual hosts and storing all the accounts under one unix account is allowed and can be mapped. But other places talking about the virtual hosts having no privileges on the filesystem and being unable to write to any files. I wish the error messages would lead me to a more conclusive answer...

No, that's just a performance tuning. If you use proxy, then there's only one MYSQL connection open which is used by all Postfix processes. If you don't use proxy, then every Postfix process which needs to access the database opens a new connection.
