[Dovecot] Using dovecot as LDA for postfix
Hi
Here is my environment: Red Hat Enterprise Linux Server release 5.7 (Tikanga) postfix-2.9.1-1.rhel5 dovecot 1.0.7
I want to config a complete postfix-dovecot mail server. First I configured postfix to use procmail, its default LDA and dovecot for pop3 and imap. I didn't changed main.cf a lot, just myhostname and a few other properties. I didn't set home_mailbox. About dovecot.conf here is the output of dovecot -n : # 1.0.7: /etc/dovecot.conf log_path: /var/log/dovecot.log protocols: imap pop3 login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd
As you can see mail_location is not set. At this time everything was OK and working. I was able to send email using SquirrelMail and thunderbird. I got two users, user1 and user2, in my linux machine and when I sent an email from user1@software.com to user2@software.com the sent mail was saved in /home/user1/mail/Sent and the received email was in /var/mail/user2. The log file for dovecot had entries like this for user1 and user2:
dovecot: Oct 14 14:44:52 Info: IMAP(user1): maildir: couldn't find root dir dovecot: Oct 14 14:44:52 Info: IMAP(user1): mbox: root exists (/home/user1/mail) dovecot: Oct 14 14:44:52 Info: IMAP(user1): mbox: INBOX exists (/var/mail/user1) dovecot: Oct 14 14:44:52 Info: IMAP(user1): mbox: root=/home/user1/mail, index=/home/user1/mail, inbox=/var/mail/user1
At this point I tried to change the LDA from procmail to dovecot by the following settings:
I added/changed the following in the main.cf:
mailbox_command = /usr/libexec/dovecot/deliver dovecot_destination_recipient_limit = 1 virtual_mailbox_domains = software.com virtual_transport = dovecot
I added the following in the master.cf:
dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${recipient}
But it didn't work. When I send email from from user2 to user1 the sent email is correctly saved in /home/user2/mail/Sent but it seems that user1 doesn't receive the incoming email. dovecot.log had entries like the following:
dovecot: Oct 14 14:54:04 Info: imap-login: Login: user=<user1>, method=PLAIN, rip=::ffff:172.27.7.8, lip=::ffff:172.16.100.183, TLS dovecot: Oct 14 14:54:04 Info: IMAP(user1): Effective uid=504, gid=504, home=/home/user1 dovecot: Oct 14 14:54:04 Info: IMAP(user1): maildir: access(/home/user1/Maildir, rwx): failed: No such file or directory dovecot: Oct 14 14:54:04 Info: IMAP(user1): maildir: couldn't find root dir dovecot: Oct 14 14:54:04 Info: IMAP(user1): mbox: root exists (/home/user1/mail) dovecot: Oct 14 14:54:04 Info: IMAP(user1): mbox: INBOX exists (/var/mail/user1) dovecot: Oct 14 14:54:04 Info: IMAP(user1): mbox: root=/home/user1/mail, index=/home/user1/mail, inbox=/var/mail/user1
Setting home_mailbox = Maildir/ in main.cf and mail_location = maildir:~/Maildir in dovecot.cf didn't help. I have been googling and reading and testing for 4 or 5 days for this but there was no chance. Now, I am stuck and any help would be really really appreciated.

So, please do not start with an ancient, unsupported version.
2.2.6 is the latest stable, but at least use the latest 2.1 version...

He's running redhat/centos 5.X; latest dovecot version for thatis 1.0.7. Only way out if he is using the redhat packages is to go to redhat 6.X, which probably means a full reinstall... which he may not be authorized to do. And even then he would be a 2.0.9.
Some of us do have to stick to the packages officially supported by a distro; I had the very same issue, which is why I was stuck with 1.2.9 in ubuntu 10.04 and now 2.0.19 in 12.04LTS. Would I love to be at least in 2.1? You betcha, but...
To the OP: you might want to see if epel or the other non-official repositories have something newer and whether your boss allows you to use them. As I mentioned above, I have run 1.2.9 until quite recently, so I still have my configs available. Don't know how much 1.0.7 differs from 1.2.9 though; you will need to check http://wiki1.dovecot.org/. But, I can paste them here. On thing I am curious about is why you have maildir and mbox at the same time.

You used a third-party RPM or SRPM for Postfix, why not for Dovecot? Also, the latest in the Postfix 2.9 series is patchlevel 6 or so.

FWIW, procmail is NOT the default LDA for Postfix. Postfix has its own local(8) and [optional] virtual(8) LDAs. Procmail is very old and unmaintained (it makes Dovecot 1.x look recent!) Only old and well- established sites should be using procmail now. There are much better options for new sites in A.D. 2013.

At this point I tried to change the LDA from procmail to dovecot by the following settings:
I added/changed the following in the main.cf:
mailbox_command = /usr/libexec/dovecot/deliver
This is used for the local domain class. It's not relevant for other address classes.
dovecot_destination_recipient_limit = 1 virtual_mailbox_domains = software.com
This defines the virtual mailbox domain address class. This says that addresses@software.com are virtual mailbox, NOT local, addresses. If you're using passwd and PAM as userdb/passdb, this is not what you want.
virtual_transport = dovecot
And this is the default transport to be used for virtual mailboxes.
I added the following in the master.cf:
dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${recipient}
But it didn't work. When I send email from from user2 to user1 the sent email is correctly saved in /home/user2/mail/Sent but it seems that user1 doesn't receive the incoming email. dovecot.log had entries like the following:

That's a system user login (local user in Postfix terms.)
dovecot: Oct 14 14:54:04 Info: IMAP(user1): Effective uid=504, gid=504, home=/home/user1 dovecot: Oct 14 14:54:04 Info: IMAP(user1): maildir: access(/home/user1/Maildir, rwx): failed: No such file or directory dovecot: Oct 14 14:54:04 Info: IMAP(user1): maildir: couldn't find root dir dovecot: Oct 14 14:54:04 Info: IMAP(user1): mbox: root exists (/home/user1/mail) dovecot: Oct 14 14:54:04 Info: IMAP(user1): mbox: INBOX exists (/var/mail/user1) dovecot: Oct 14 14:54:04 Info: IMAP(user1): mbox: root=/home/user1/mail, index=/home/user1/mail, inbox=/var/mail/user1
Setting home_mailbox = Maildir/ in main.cf and mail_location =
The home_mailbox setting IS relevant to local domains.
maildir:~/Maildir in dovecot.cf didn't help. I have been googling and reading and testing for 4 or 5 days for this but there was no chance. Now, I am stuck and any help would be really really appreciated.
This is mostly a Postfix question, BTW, so I will point to to the Postfix documentation. Don't confuse your address classes:
