Postfix + imap without mysql

CoolCow · 06-04-2008, 03:51 AM

Hello,

I'm having troubles configuring postfix with imap support.
I've used this tutorial to install postfix with imap.
But now i'm wondering if i can create users without using mysql for storing the accounts.
I only need 3 users and postfix should run as fast as possible, that's why i don't want to use mysql.

Is this possible, or is mysql required once imap is used?

Where does the tutorial even mention mysql?

Postfix by default will pick up unix style users from /etc/passwd, so add those users using useradd and their mail should appear in /home/their_username/Maildir.

fyi, mysql isn't a default option as far as I recall, and the RH packages don't come with it in any case. here's a snippet from the postfix site on making with mysql support

Code:

make -f Makefile.init makefiles \
    'CCARGS=-DHAS_MYSQL -I/usr/local/mysql/include' \
    'AUXLIBS=-L/usr/local/mysql/lib -lmysqlclient -lz -lm'

I'm sorry, i mixed up the tuts i used, it was this one.

Now i already created the users when i first started postfix without courier imap (as discribed in another tut) but that doesn't seem to work.

When i try to telnet imap i get this:

Code:

# telnet localhost imap
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.

X login mailer ***masked***
* BYE [ALERT] Fatal error: Maildir: No such file or directory
Connection closed by foreign host.

So there's still something wrong with the users.
And when i look at /home/mailer there is no Maildir directory...

Create

~/Maildir
~/Maildir/cur
~/Maildir/new
~/Maildir/tmp

where ~ = /home/relevant_username

all owned by the user and permissions 700

Thnx, that did the trick, must of missed something in the tut.

Another postfix related question.
I'm using imap with php. When i login using the imap_open function in php i must provide the /notls option.
Is is possible to disable ssl/tls by default?

Probably, but I use dovecot not courier-imap, so I can't help you there

One last thing

Postfix is running perfectly but there's one configuration problem i can't seem to find.

Using SMTP i only want postfix to allow e-mails being sent from localhost and/or a certain domain.
I've tried enabling smtpd_reject_unlisted_sender but i still can send from any domain.

e.g.: the MAIL FROM: should only allow <variable>@my-domain.com
