[Dovecot] dovecot-uidlist crashing and re retriving messages by pop3 clients

[Piotr Rotter]

Thank you for your assistant.

Broken uidlist errors appears more than 10 time less frequently then in 
the past and still reduce.

I have question about director and no plain text auth methods. Now I 
have tricky query in director configuration.
password_query = SELECT clear AS password, 'Y' as proxy, '%u' AS 
destuser, clear AS pass FROM postfix_users WHERE email = '%u'

Is there some method to make it better. Master password is a bit 
dangerous ( man in the middle ). Is director can relay no plain text 
authorization with out checking.

I have one more question, which is not concerned subject above. Is there 
any chance to set dovecot to be policy demon for postfix to check 
mailbox quota before mail are checking  by (amavis, spamassassin, 
clamav) and before it is sending by lmtp. I think that it could  reduce 
load.
