I am using gentoo and dovecot 2.2.19. I get numbers for all columns except disk_input, disk_output, read_count, read_bytes, write_count and write_bytes which is 0. cat /proc/self/io rchar: 2068 wchar: 0 syscr: 6 syscw: 0 read_bytes: 0 write_bytes: 0 cancelled_write_bytes: 0 Is this a kernel setting that causes this read_bytes and write_bytes to be 0 as it happens on a test server as well. /Kilburn
Dovecot top stats
Hi, I have being try to track down top email users to sometime. When I do a network traffic check I can see there is about 15 times more email traffic pulled from mail server than sent. The problem I am trying to track down is which users are the culprit. I have enabled doevcot stats and I can do a doveadm stats dump user but I get a 0 for disk_input, disk_output, read_bytes and write_bytes. I do get mail_read_bytes numbers but I am not sure these numbers are correct. I there a top utility that works well so I can see email traffic from users mailboxes. The doveadm top does not work well. I also tried the perl scripts and that does not do a much better job. Thanks Kilburn

It seemed to reduce the error a bit but I don't know if this is factor of mail reduction or headers. Either way, there is a regression in 2.2.
Re: [Dovecot] Outlook 2007 2010 hangs in v2.2?
I can confirm also that since upgrading from 2.1.16 to 2.2.13 that Outlook 2013 (don't have previous versions to test) is throwing strange errors when users send emails. This predominantly happens when sending but has happened when they compose a long email then send. These users have 50GB+ mailboxes using IMAP. I will try the fetch headers and report back. The Outlook errors we are getting is The operation failed. The messaging interfaces returned an unknown error. Please restart Outlook. So I can confirm there is problem, as one of the users who use Thunderbird with an equally large mailbox and does not have problems.

For users with large mailboxes, they are unable to sync their folders. Perhaps this is specifically because of the problem you are mentioning Timo. The only solution we could come up with for now was to configure outlook to only fetch headers and not bodies, when syncing. For the most part, bringing up individual messages is fine, haven't seen that fail. So, with that tweak to the outlook config, things are working error-free again for our users...but it was certainly an unexpected situation to tackle. Also, we found a marked improvement connecting via SSL on 993 than we do unencrypted on 143. I can definitely confirm 100% there is a regression in dovecot 2.2 that severely impacts the performance of outlook (but works great with everything else). Let me know if I can help you track this down Timo.

I can't think of any reasonable explanation for this. how large? I don't know yet if the mail size is even relevant. At least one hang was caused by downloading ~55 MB mail where it stopped just before the last 400 kB. I find it strange that v2.2 has been out for a long time and nobody before this complained about any hangs. 55 MB mail may are rare ,i can test it ,but it will need some time ( old outlook install on clean new windows system) perhaps anyone has an existing setup which could do it faster Happens also with smaller mails, for example 3 MB and I think there were also even smaller ones like 1 MB. I see that once Outlook tried to download the same 3 MB mail 3 times and it stopped reading it when it had 400 kB left, but the 4th time succeeded. Dovecot sent exactly the same data with the same TCP packet boundaries all times (at least to Dovecot proxy - would have to look with tcpdump further to see if proxy does something differently..) Anyway, nobody in general has had trouble with Dovecot v2.2 and Outlook 2007/2010? Maybe the problem is something else, although strange if it started happening only immediately after Dovecot upgrade.

[Dovecot] correct syntax for multiple ports
Hi,
What is the correct format to specify multple ports in dovecot 2. With
dovecot 1.2 listen = *:143 *:6188 worked fine. I cannot find any mention
in the wiki2 about the different combinations of listen, address and
port parameters and dovecot complains about the combinations I tried.
Does not seem to work
1. inet_listener imap {
listen = *:143 *:6188
}
2. inet_listener imap {
address = *:143 *:6188
}
3. inet_listener imap {
port = 143, 6188 or port = 143 6188
}
This start dovecot, but roundcube will not connect on port 143, although
Thunderbird will connect on 1432 and 6188
listen = *, ::
1. inet_listener imap {
port 143
port = 6188
}
Regards

OK, it seems that it's needed to specify multiple ports this way:
service imap-login {
inet_listener imap {
port = 143
}
inet_listener imap_second {
port = 6188
}
}

Ok, that works. Is this listed somewhere? What is the syntax if you want
to add more ports.

Re: [Dovecot] Migrating from CommunigatePro to Dovecot - anyone done this?
Migrated 300+ mailboxes a few days ago (pop-imap and imap-imap) using imap tools from http://www.athensfbc.com/imap_tools/. Use v1.74 tar file. The author fixed a date issue. For some reason Dovecot expects that time format to be 2 characters, so for example 2:10:41 will fail but 02:10:41 will pass. After the script was changed all went very smooth. You can use the mass migration tools (migrateimap.pl and pop2imap.pl) I did not have much luck with imapsync. Regards Kilburn On 17/06/2010 12:44 AM, Gavin Lawrie wrote: Arne, Timo Really helpful suggestions. Thanks! imapsync looks like it will do the job - I think I can get the two servers to co-exist on the same server, so bandwidth issue will be minimised. Presumably also it will negate the need to convert each user to having just MailDir directories before the move I will have a think about the script / dsync solution - if it turns out to be useful over imapsync and I create anything useful I will of course share it back via list etc. Regards Gavin * Balanced Scorecard Training from 2GC: Next course 16th July 2010 in the UK.
