Hi

For the last couple of years I´ve been using postfix along with
courier-imap, but now I´m going to switch to cyrus, and have followed
the guide from postfix.org -> doc -> Postfix+Cyrus+Web-cyradm howto by
Luc de Louw (http://www.delouw.ch/linux/postfix.phtml)

However that causes me some trouble, when I send testmails, they´re
bounced with "Mailbox does not exist". I can´t see what I´ve missed (or
if it´s a postfix or cyrus problem for that matter :-) Anyone running a
similar setup, who´s got a clue?

Here´s a bit of the maillog:

move back to courier-imap, since it apparently worked for you. if your
mda/imap/pop/webmail server doesn't do what you want, ask on its mailing
list.

Postfix delivers messages to em...@emax.dk to Cyrus, telling Cyrus that
it should deliver the message to the user emax. Is that what should've
happened? If so, this is not a Postfix problem. Investigate and ask on
a Cyrus list why Cyrus doesn't think emax is a valid recipient. Perhaps
Cyrus expects fully qualified addresses and not bare usernames? If so,
modify the cyrus line in master.cf to send something other than ${user}
to deliver. Anyway, invoke the deliver program from the shell until you
get it working. Only then should you try to get it working with Postfix.

My _current_ setup is running courier-imap, i´m testning a new setup
cause I need to assign quota on each user individual.

Assuming you are using virtual users and can't use the file system
quota system, you do know that Courier-IMAP supports per-user quotas?

No, had no idea. I´m using courier-imap-3.0.8, and as far as I remember,
that wasn´t possible and I´ve never check if it later could support
it... I´ve tried sometime ago to upgrade to courier-imap-4.0.3, but that
didn´t work at all, so I dropped that again (don´t fix it if it ain´t
broken). Later I was told that cyrus could what I wanted, so I looked
into that. I´ll check the doc for the lates courier...

Thank You for the info.

You didn't show, that you have created the Mailboxes "emax" and "root" in
Cyrus-Imapd. Did you?

Ah! That's the same method that I used.
It's not completely perfect, I must say.
I have everything working, but it took some time and sweat to get
there. For one, the described configuration doesn't force postfix to
query the MySQL database for existence of the mailbox.
That's wrong, because postfix will then accept email for non-existent
mailboxes, and send a bounce message later (when the local delivery fails).
The correct configuration should make postfix query the MySQL database
for the existence of the mailbox and reject the message during the
SMTP-session. No bounce message needed.

The mailbox DOES exist in Cyrus, no?
Then you should check how the mailboxes are named in Cyrus and in
your MySQL database. The names should match, of course.

And you should configure postfix to verify the existence of the
mailbox by querying the MySQL database, so it can reject email
messages for nonexistent mailboxes BEFORE queueing them.
Here are some settings from my main.cf postfix configuration file:

virtual_alias_maps = hash:/etc/postfix/virtual, mysql:/etc/postfix/mysql-virtual.cf
virtual_mailbox_domains = mysql:/etc/postfix/mysql-vmailbox-domains.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql-vmailbox.cf
local_recipient_maps = unix:passwd.byname, $alias_maps, mysql:/etc/postfix/mysql-local-maps.cf
relay_recipient_maps = mysql:/etc/postfix/mysql-relay-recipients.cf
sender_canonical_maps = mysql:/etc/postfix/mysql-canonical.cf

Query specifications in my mysql* files:

mysql-virtual.cf:
dbname = mail
table = virtual
select_field = dest
where_field = alias
additional_conditions = and status = '1'

mysql-vmailbox-domains.cf:
dbname = mail
table = domain
select_field = domain_name
where_field = domain_name

mysql-vmailbox.cf:
dbname = mail
table = virtual
select_field = dest
where_field = alias
additional_conditions = and status = '1'

mysql-local-maps.cf:
dbname = mail
table = virtual
select_field = alias
where_field = alias

mysql-relay-recipients.cf:
dbname = mail
table = virtual
select_field = alias
where_field = alias

mysql-canonical.cf:
dbname = mail
table = virtual
select_field = alias
where_field = username
additional_conditions = and status = '1' limit 1

This happens to work great for me. YMMV though.
I didn't change the database structure, it's exactly the database
structure as described by Luc de Louw. When some MTA tries to address
(MAILTO) a user for whom no mailbox exists, then the message is
rejected and postfix logs a 550 NOQUEUE record with the text
"<email-address>: Recipient address rejected: User unknown in virtual mailbox table"

Once again: this works for me.
If you or somebody else has any improvements on this example, then
please let me know. I'm always in for learning new tricks. :-)

Regards,
Toon.

Interesting... I´ll look into that. Such a mail will be rejected with a
556 then?

> The mailbox DOES exist in Cyrus, no?

Where Do I look for that? I haven´t found a setting that tells cyrus
where to put the mail... so it must be at the default location...

I my current running setup (courier) I use /data/mail/DOMAIN/USER/Maildir/

I can see that the web-cyradm adds a file in /var/mail/

[root@serv010 root]# ls -al /var/mail/
total 140
drwxrwxr-x 2 root mail 4096 Nov 3 01:06 .
drwxr-xr-x 14 root root 4096 Oct 26 17:40 ..
-rw-rw---- 1 cyrus mail 0 Oct 26 17:39 cyrus
-rw-rw---- 1 emax mail 0 Sep 8 21:33 emax
-rw------- 1 root root 130150 Oct 8 19:25 root

However it looks strange that emax should have been created to months ago...

The mailbox emax exists in MySQL

I have 1200 spammer adresses in a MySQL table that I block, You can have
those? :-)
