[Dovecot] Weird log entries when some users are composing messages in Thunderbird

[Charles Marcus]

Hi all/Timo,

When some of our users are composing a message in Thunderbird, I see a 
ton of these in the logs, and they keep repeating the entire time they 
are typing until the message gets sent...

> 2013-08-05T10:34:42-04:00 myhost dovecot: imap-login: Login: user=<user at media-brokers.com>, method=PLAIN, rip=###.###.###.###, lport=993, mpid=8152, TLS, session=<El2GNTTjNgDAqAIc>

I confirmed that their 'Auto-Save' settings are the defaults (5 minutes, 
same as mine), and when I'm composing a message, there are no entries 
like this. The only other option I could think of that might affect t 
his is the 'spell check as you type', which is also enabled on mine.

Also - I'm not sure this *always* happens to these users... all I know 
is, I see these flooding the logs sometimes, and when I remote in, that 
user is composing a message.

Anyone have any idea why this happens to only a few of our users, and 
possibly only sometimes? Could it be something in the HTML of the quoted 
text when they are replying to certain messages?

Thanks,
