[Dovecot] Log successful login plain text password

[wkaha at yahoo.com]

Cool.

I tried doing the same.
I've installed a proxy with the smallest possible setting

----dovecot.conf----------------------------
protocols = imap
ssl = no
mail_uid = dovenull
mail_gid = dovenull
first_valid_uid = 143
first_valid_gid = 143
auth_mechanisms = plain login
auth_debug_passwords=yes
mail_location=imapc:~/imapc
mail_home = /home/%u
imapc_host = server.name.com
imapc_port = 143
passdb {
  args = host=server.name.com
  default_fields = userdb_imapc_user=%u userdb_imapc_password=%w
  driver=imap
}
userdb {
  driver = prefetch
}

-------------------------------------

and the result in my logs was

----
Aug 30 15:06:23 free92 dovecot: auth: Debug: master userdb out: USER	12341234124	username at server.name.com	imapc_user=username at servername.com	imapc_password=ClearPassword	auth_token=***some token***
----

that's nice for migrating servers.

all the best
