[UPDATE]:
I digged deeper into my logs and I found that before the upgrade I got this
errors:
...

After the upgrade the errors above stopped and now they look like this:

or

First I didn't see the first errors as they are only written to "mail.log" and not
"mail.err" in Debian.
So I think this is not really critical as there are no user complaints right
now.

Hi,
first of all, many thanks for a great piece of software.
Today I updated one of our 2 IMAP/POP3 proxies from version 2.2.15.17-1 to
2.2.23.1-1 (both are enterprise editions).
After the update I now see randomly the following errors in the log file on my
first proxy:

Some more details:
OS: Debian wheezy (latest patchlevel)
Dovecot:
ii dovecot-ee-core 2:2.2.23.1-1
ii dovecot-ee-imapd 2:2.2.23.1-1
ii dovecot-ee-managesieved 2:2.2.23.1-1
ii dovecot-ee-mysql 2:2.2.23.1-1
ii dovecot-ee-pop3d 2:2.2.23.1-1
ii dovecot-ee-sieve 2:2.2.23.1-1
Libssl:
ii libssl1.0.0:amd64 1.0.1e-2+deb7u20
One my second proxy there is running also Debian Wheezy with the latest
patchlevel but dovecot version 2.2.15.17-1 (not yet updated):
ii dovecot-ee-core 1:2.2.15.17-1
ii dovecot-ee-imapd 1:2.2.15.17-1
ii dovecot-ee-managesieved 0.4.6-4
ii dovecot-ee-mysql 1:2.2.15.17-1
ii dovecot-ee-pop3d 1:2.2.15.17-1
ii dovecot-ee-sieve 0.4.6-4
On this box I can't see this strange errors.
Until now there was no user that complaints that he can't read his mails.
Do you know what could cause this errors (for example: very old clients and so
on)?
Or are the logging of this errors new in dovecot 2.2.23?
Many thanks
Urban Loesch
