Old-stats plugin and fifo_listener permissions

2022-09-09 Thread Grant Keller 
Hello,

Currently working on using the old-stats plugin in dovecot version
2.3.10.1. What file permissions are recommended for the old-stats-mail
and old-stats-user sockets? I was seeing a lack of data from the doveadm
oldstats dump command until I adjusted the default config to the
following:

service old-stats {
  fifo_listener old-stats-mail {
group =
mode = 0666
user = root
  }
  fifo_listener old-stats-user {
group =
mode = 0666
user =
  }
}

Not totally clear on which processes need read or write on those so any
advice is appreciated.

Dovecot fixing maildir message size?

2022-01-06 Thread Grant Keller 
We recently updated dovecot from 2.1.17 to 2.3.10. It used to be when we
encountered the following error:
Jan  6 15:29:20 d.imapd.sonic.net dovecot: imap(momomo): 
session=aBd2O/LULMu4F6ia Error: Mailbox INBOX: UID=1: 
read(/var/spool/mail/07/00/momomo/cur/1510707300.12345_0.a.spam,S=1234:2,) 
failed: Cached message size larger than expected (1234 > 704, box=INBOX, UID=1) 
(read reason=)
Dovecot would fix the size by renaming the file. Now this doesn't appear
to be the case. Was there a change in behaviour, or is there an option I
need to enable now to have dovecot auto fix this?

mail_location for doveadm?

2021-11-04 Thread Grant Keller 
Hello,
I am working on getting doveadm commands working from a director to a
backend server and I am hitting a bit of a roadblock. We use a homebrew
hashing algorithm for mail_location, which we set for users in postlogin
scripts. Works fine except I get the following when I run doveadm on a
user:

I don't see anything like a doveadm-postlogin service in the
documentation, so how would I go about making this work.

Re: Issue with the log service after upgrading from 2.1.17 to 2.3.10.1

2021-10-04 Thread Grant Keller 
Dug a bit more because we are still seeing this issue after upgrading.
Apparently this error has to do with a high rate of log messages:
Oct  4 16:54:39 f.imapd.sonic.net dovecot: log(30450): Warning: Log connection 
fd 34 listen_fd 34 prefix 'imap-postlogin: ' is sending input faster than we 
can write
But how do I determine what is doing so much logging? The mail logs on
the system seem fine. This server in particular has had that same
warning for 4 days, with the corresponding log process consuming 100%
cpu. There is no stuck postlogin script spewing to the logs that I can
see.

Issue with the log service after upgrading from 2.1.17 to 2.3.10.1

2021-09-30 Thread Grant Keller 
Hello,

As stated in the subject we have been doing a pretty big version
upgrade. Both new and old are on CentOS 7. For the second time, one of
our upgraded servers have had the dovecot log process start consuming
100% cpu, and the strace output shows it trying to access
/etc/localtime:
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0

With no other output then that multiple times a second. The process
itself shows this from ps:
root  76106  8.3  0.0  15384  6532 ?RSep29 140:21 dovecot/log 
[service too fast: 34/34/imap-postlogin: ]
As a part of this upgrade we also modified our postlogin script to
include an index location for each user, so I am not sure if this is
related to that change or a change in the logging service. Any help
tracking this down is appreciated.
