Mail User Agent?

Hi,is there a way to log which MUA is being used from an user?
# dovecot  --version2.0.9
Thank you

TLS SNI Client Support

2016-01-12 Thread absolutely_f...@libero.it

Hi,according to this page:
http://wiki2.dovecot.org/SSL/SNIClientSupport (last change 2013)

I would like to know if this limitation is still valid.
# dovecot --version2.0.9
I am trying to configure Android default email client and I am not able at all 
to use TLS.
With other clients I have no problem, so I think my server configuration is ok.
Thank you

Performance

2015-04-24 Thread absolutely_f...@libero.it

Hi,

at moment I have this environment:

CentOS 
nginx + phpfpm
Dovecot, with Maildir format
Postfix
Roundcube 
MySQL backend
about 1 mailusers
dual core Intel(R) Pentium(R) D CPU 3.00GHz
8 GB RAM
network storage device (Coraid), ext4 file system 

I have no performance issue now, but I need to move to a different  server:

FreeBSD 10.1-RELEASE
nginx + phpfpm
Dovecot
Postfix
Roundcube 
dual core Intel(R) Xeon(R) CPU5120  @ 1.86GHz
16 GB RAM
local storage with zfs file system

My question is: is better to use SQLite instead of MySQL?
Should I prefer dbox format?

Thank you in advance for your opinion!

 Hi Angel,
 can you please share your dovecot configuration?

   I have attached our doveconf -n output. We have two imap servers (with 
the same configuration) and two more acting as proxy (with director) in 
front of them. These last direct user request to their corresponding server.

   For storage we are using our SAN (a HP 3PAR 7400) connecting to it with 
fibre channel. We have two XFS filesystems. One for mail indexes and the 
other for user mailboxes and attachment files.

   In these servers we are running ubuntu 12.04 with kernel 3.4.0.

 What webmail are you using (if any)?

   We are using horde.

What happen if I manually delete some messages (eg. the ones older than 6

 It's a network attached storage (Coraid).
 In your opinion, what is the best file system for mail server 
(pop3/imap/webmail) purpose?

 Depends on what OS you have chosen, or if OS is not the limiter I would go 
with ZFS.

   Have you any performance comparison with xfs?

   I'm running two imap servers. One with about 9k accounts and 3.5TB of 
storage, and another with 55k accounts and 2TB of storage with XFS, and 
I'm thinking about migrating them from XFS to ZFS but I'm concern about 
IO performance of ZFS. When we developed these two servers, I remember 
reading some zfs performance problems in comparison with xfs (I have 
lost the link) and that was the reason to finally use xfs, but now we 
are having problems with LVM snapshots and we also like some zfs 
features (like replication) so we are thinking about the change.

Performance issue

2014-11-05 Thread absolutely_f...@libero.it

Hi,
Since few days I noticed very high load on my mailserver (Centos 6.6 64bit, 8 
GB RAM, 2 x  CPU 3.00GHz 
I am using Dovecot + Postfix + Roundcube + Nginx.

I have about 1 users.
Spool is on network attached storage (Coraid).

File system is ext4 (mounted with noatime).

Problem appears almost every morning (while load is normal during afternoon).

I suspect that this can be related to some user that have so many messages in 
his mailbox.
How can I troubleshoot this?

Here some messages that I got in maillog:

Warning: Maildir: Scanning /var/spool/pop/domains/.it/Y/Maildir/new 
took 71 seconds (1 readdir()s, 1 rename()s to cur/)

Warning: Maildir /var/spool/pop/domains///Maildir/.Trash: 
Synchronization took 74 seconds (5 new msgs, 0 flag change attempts, 0 expunge 
attempts)

dovecot: imap(x...@.it): Warning: Inotify instance limit for user 89 (UID 
postfix) exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_instances


tail: inotify cannot be used, reverting to polling: Too many open files

My relevant dovecot conf:

mail_location = maildir:/coraid-s2l2/domains
namespace {
  type = private
  separator = .
  prefix = INBOX.
  inbox = yes
}
mail_uid = 89
mail_gid = 89
mail_fsync = never
first_valid_uid = 89
first_valid_gid = 89
maildir_very_dirty_syncs = yes
mbox_write_locks = fcntl



thank you very much!
