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_postfix_mysql_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: connect from cpe-x-x-x-x.satx.res.rr.com[x.x.x.x] Jan 11 22:08:22 mail postfix/smtpd: 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/cleanup: D62AD4832496: message-id=<43C5C841.email@example.com> Jan 11 22:08:23 mail postfix/qmgr: D62AD4832496: from=<firstname.lastname@example.org>, size=568, nrcpt=1 (queue active) Jan 11 22:08:23 mail postfix/smtpd: disconnect from cpe-x-x-x-x.satx.res.rr.com[x.x.x.x] Jan 11 22:08:42 mail postfix/virtual: 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: warning: process /usr/lib/postfix/virtual pid 7798 exit status 1 Jan 11 22:08:43 mail postfix/master: 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------- D62AD4832496* 568 Wed Jan 11 22:08:22 <username>@hidesato.com <username>@hidesato.com -- 0 Kbytes in 1 Request. 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.
