Change password schema and post-login script

[Christos Chatzaras]

Hello,


Question #1:

For version 2.3.19.1 these commands use BLF-CRYPT, right?

doveadm pw
doveadm pw -s CRYPT


Question #2:

I want to change password schema for current users.

For users using POP3 or IMAP I can do it using a post-login script.

I have some accounts used only to send e-mails using Postfix, so no POP3/IMAP logins for these accounts.

Is any way to change password schema for these accounts?


My config:

# Pigeonhole version 0.5.19 (4eae2f79)
