dovecot - Feb 2013 - Suggestions for upgrading dovecot 1.0.7 Redhat EL 5.x

Hi,

we still have our solid rock dovecot 1.0.7 Redhat el 5.x up and running.

We don't need much magic or special setups.

However we'd like to think what might be the next step in upgrading our
setup. Each user one mbox mailbox. About 500 imap/pop3 accounts, 400GB data.

First of all: to what version is a good step from 1.0?

Can we get a rpm from e.g. atrpms repository?

Dose anyone has any experiences in doing such a "big" step forward?

Or should we think of migrating to a total updated Redhat EL 6.x /
Dovecot 2.0.x system?

Any suggestions and comments are welcome.

	Regards . G. Reinicke

The configuration has been split up since v1.0, but you can grep through 
the files and find the spots easily. Also, if you didn't changed much in 
v1.0 (that is how I understand your "don't need much magic or special 
setups"), the chances are good, that you'll not change much in v2.1 or 
v2.2.

I would setup a Dovecot v2.2 server, it's RC2, but Dovecot is usually more 
stable than other software ... .

However, I would install the whole server anew, no automatic upgrade or 
whatsoever.

I have upgraded a v1.0 to v2.1 now. No big deal from Dovecot.

Ah, OK, then use the most current version available :-) I build Dovecot 
from source.

I don't know Redhat, but it seems to be wise to upgrade. What's the
"Known
Bug List" or "Known Security Holes" in Redhat EL 5.x?

Hi folks,

after some different considerations, we decided to do "just" a minor
upgrade on the old/current hardware and OS version.

We did the rpm upgrade from 1.0.x to 1.2.x and for now there are no
problems. Just a few more warnings regarding "Corrupted index cache
file".

But no user complains. From my POV there is a significant performance
boost on my large mailboxes...

At the time we can get new hardware and maybe change some other things
in our setup we will go wit 2.x I bet.

	so thanks for al the feedback! Regards . G?tz
