[wachira]

All my instalation went well only to the point were I install ISPconfig I get
Dovecot Imap: Error: mail_plugin_dir: Can't access directory: /usr/lib/dovecot/imap/: No such file or directory Fatal: Invalid configuration in /etc/dovecot.conf.
I have tried all the postings northing seems to be working. Can some one help me out on this one.

[till]

1) Which Linux distribution?
2) Is this a 32Bit or 64Bit system?

[wachira]

I am running Centos 5.5 and its a 32 bit system

Which tutorial (URL) did you use to set up the server?

What are the outputs of

ls -la /usr/lib/dovecot/imap/
ls -la /usr/lib64/dovecot/imap/

?

I used http://www.howtoforge.com/perfect-se...64-ispconfig-3. But i would replace the 64 bit part with i386.

The out puts for
[root@wachkama ~]# ls -la /usr/lib64/dovecot/imap/
ls: /usr/lib64/dovecot/imap/: No such file or directory
[root@wachkama ~]# ls -la /usr/lib/dovecot/imap/
ls: /usr/lib/dovecot/imap/: No such file or directory

Did you run this command

rm -fr /usr/lib/dovecot/
