[imp] IMP and SMTP-AUTH problem

[Andreas Ladanyi]

Hi,

Situation:
==========

Horde 3.1.5 / IMP 4.1.5

IMAP and SMTP-AUTH are working smoothly with telnet and with Thunderbird 
Client.

The IMAP and SMTP-AUTH uses the same user database via SASL. 
(dovecot-auth + postfix)

I could authenticate me and get my mails also with IMP and IMAP, but if 
i wont to send a mail i get the message:

PLAIN authentication failure [SMTP: SMTP server does not support 
authentication (code: 250, response: .....hostname.... PIPELINING SIZE 
10240000 VRFY ETRN ENHANCEDSTATUSCODES 8BITMIME DSN)]

In Horde "Mailer" tab i setup up the following:

"Use SMTP Server"
server to connect is default [localhost]
Port 587 (submission)
local hostname/domain is default [localhost]
SMTP Auth. "PLAIN"
Username and password for SMTP Auth. are empty


Did i go correct supposition Horde/IMP get the username/password for 
SMTP-AUTH from login username/password ?

Bye,
Andy
