qmail Cannot auth with smtp

[skrieg2]

Hello,

I'm trying to auth with telnet on the smtp service but I can't. E-mail clients work just fine.

Creating the base64 auth string:

$ perl -MMIME::Base64 -e 'print encode_base64("user@domain.com\0user@domain.com\0mypass");'
ZmgvcmlhbmUuxx3JnAtZvbGxleQ==

Telneting :

$ telnet myserver.com 25
Trying my.ip.ad.dre.s....
Connected to myserver.com
Escape character is '^]'.
220 hostname ESMTP
ehlo mydomain
250-hostname
250-AUTH=LOGIN CRAM-MD5 PLAIN
250-AUTH LOGIN CRAM-MD5 PLAIN
250-STARTTLS
250-PIPELINING
250 8BITMIME
auth plain ZmgvcmlhbmUuxx3JnAtZvbGxleQ==
535 auth failure

Server log says:

smtp_auth: smtp_auth: FAILED: mypass - no such user from [email]unknown@1-2-3-4.myadslip.com[/email]

Some facts :
* The same login/password works when poping with telnet and with any mail client (pop and smtp)
* The server is a 8.1 Plesk installed on Debian Sarge.
* The only modification made is the "-Rt0" in /etc/xinetd.d/smtp_psa

Note that "mypass" is in the logs where there is usually a login... maybe my auth creation is wrong ? It's weird because the Plesk's knowledge base says to do so.

many thanks for some help

> encode_base64("user@domain.com\0user@domain.com\0mypass");

why do you type login twice there? the correct view is

encode_base64("\0mailname\0passwd")

Hi,

I had to write
encode_base64("\0user\@domain.tlc\0pass");

Note the "\@".

solved
my mistake.
thanks
