IMAP ALERT on reason/nologin

[Pedro Ribeiro]

Hello everyone,

Some dovecot versions (years!) ago. I've made a rather complicated SQL 
query that verified some conditions during the SQL passdb checking and 
returned the usual parameters or "nologin" field signalling some account 
problem and a text on the "reason" field that were shown to the user 
telling him the reason of being rejected the login.

Common "reasons" are blocked accounts, suspected brute-force to the user 
account, historic problems from his IP address, etc.

In the current versions I've found that despite the attributes being set 
by the SQL query, dovecot no longer seems to signal that to the client 
application and it ends with some generic "wrong password" causing a lot 
of confusion and user complains.

I can't find any reference to that (nologin/reason) logic in the current 
Dovecot documentation.

Is this feature deprecated/removed?

Were that logic changed and documented elsewhere?

regards! stay safe!

Note: running Dovecot 2.3.10.1
