At the end of each IMAP command Dovecot checks if there have been 
external changes to mailbox (eg. by another IMAP client). If flags have 
changed, the flag changes are sent to client. This is how IMAP 
specification defines it should work.

Strange. UW-IMAP at least does the same thing, and I'd have thought 
Cyrus also does it, so this shouldn't be a Dovecot-specific problem.. 
It's definitely a Squirrelmail bug anyway.

Looks like you're using Squirrelmail at the same time you have another 
IMAP client open since you have those Junk-flags added. Most people 
probably don't do that which is why Squirrelmail doesn't break with

That's because the Junk flags get added only to INBOX by Thunderbird or 
Apple Mail.

Yep. I think Squirrelmail should be fixed. If this problem occurs for 
other IMAP clients too, I might add yet another workaround option to 
fix this.
