Jan 26 14:04:38 server dovecot[2592]: Dovecot v1.0.rc15 starting up


i have no idea how to fix this.
 
Code: 
Jan 26 14:04:38 server dovecot[2592]: Dovecot v1.0.rc15 starting up

i think this is that latest i will run the update script and see.

i have updated exim and dovcot although i think they were the latest versions and i still ahve the problem.
 
Hey,

Code: 
Jan 26 14:04:38 server dovecot[2592]: Dovecot v1.0.rc15 starting up

Dovecot is up to v1.0.rc19 last time I looked.

BTW: It's Exim that sends the mail, not Dovecot...

Hey,

It's saying it's a permission problem so...

What does:

# ls -l /var/spool

and

# ls -l /var/spool/exim

show?

And just for grins:

# df

Click to expand...

Your input directory looks like the problem. Only root will be able to write files to that directory and exim runs as mail not root. Try doing this:
Code: 
chown mail /var/spool/exim/input
chgrp mail /var/spool/exim/input
chmod 710 /var/spool/exim/input
 
after i updated exim it wont start when i try and install with the update.script thing i get

Hey,

I believe you need the "db4-devel" package...

Try:

yum install db4-devel

Then you can try Wael's update script.

Don't forget Toms' post that shows you how to fix the permissions... You might do that first...
