I had this problem running Dovecot 2.x where LDAP servers are located on
another firewall zone, we use Juniper SSG550. The problem was that the
firewall was dropping the ldap idle connections so client authentication
was failing in dovecot for a while and after a time it reconnects,

I'm having a problem with dovecot ldap connection when ldap server is in
another firewall zone, firewall kills the ldap connection after a
determined period of inactivity, this is good from the firewall point of
view but is bad for dovecot because it never knows the connections has been
dropped, th
Hi, just to let you know to all the people testing dovecot in a RHEL 6.1
setup where nodes are Active/Active and sharing a GFS2 filesystem that there
is a bug on latest rhel6.1 GFS2 kernel modules, and latest updates in 6.0
wich makes dovecot crash a GFS2 filesystem, with a corruption and other
re
ideas???

Hello list, we continue our tests using Dovecot on a RHEL 6.1 Cluster
Backend with GFS2, also we are using dovecot as a Director for user node
persistence, everything was ok until we started stress testing the solution
with imaptest, we had many deadlocks, cluster filesystems corruptions and
hangs,
Thanks Ed, right now we are finishing the setup, next week we will continue
the tests and will let you know the results...
best regards

We have used sdbox as mailbox format, and all the user data is configured in

We have done some benchmarking tests using dovecot 2.0.12 to find the best
shared filesystem for hosting many users, here I share with you the results,
notice the bad perfomance of all the shared filesystems against the local
storage.
Is there any specific optimization/tunning on dovecot for use GF
Hi people, I have a setup configured using ldap, I have noticed that after a
period of user inactivity if a client open connections to dovecot first
attemps fails with this:
Nov 16 19:34:43 cl05-02 dovecot: auth: Error:
ldap(u...@xxx.xx.xx,172.29.13.26):
Connection appears to be hanging, reconnect
Found it:

It would be great if director include it self this feature..

Hi people, I know I saw this at some point in the list but can't find it, I
need a script wich monitor the health of the email backend and if a node
fails remove it from the director server, once is up again add it, I plan tu
run the script at the load balancer, if you have some let me know..

Read this in GFS2 docs:
mmap/splice support for journaled files (enabled by using the same on disk
format as for regular files)

Should I set mmap_disable = yes when storing indexes in a GFS2 shared
filesystem??

Hi, all
this days I'm testing a dovecot setup using lvs, director and a cluster
email backend with two nodes using rhel5 and gfs2. In the two nodes of the
email backend I configured mail location this way:
mail_location =
sdbox:/var/vmail/%d/%3n/%n/sdbox:INDEX=/var/indexes/%d/%3n/%n
/var/vmail is
Just that, wich is the recommended quota backend for sdbox in terms of
performance and flexibility running a setup of virtual users with ldap??...
thank's in advance...

Hi to all in the list, we are trying to do some tests lab for a large scale
mail system having this requirements:

- Server side filters.
- User quotas.
- High concurrency.
- High performance and High Availability.
We plan to test this using RHEL5
