dovecot - Jun 2016 - password expire warning for dovecot users in IMAP/POP login

Aki-san,

Thanks for your feedback.

Whatever ways will do.  For instance, in a thunderbird mail client, a 
pop-up message or notification email telling client that the password 
will be expired in XX days, something like this, would be nice.

Thanks,
Masaharu Kawada

IMAP has ALERT response which is supported by some clients. I think
Thunderbird supports that. I don't think POP has such a feature, but I
wouldn't care about POP.

Alec-san,

Thanks for your comment.

Please lemme make sure one more thing.

 >IMAP has ALERT response which is supported by some clients.

To make it happen, no need to add any other configurations on LDAP end 
once possword policy is correctly set?

Thanks,
