Topic: SMTP to ISP Authentication Problem

[azche24]

Hi,

i am using SME on ADSL line (dynamic IP), so i have to upload emails to my ISP for delivery. My ISP added an extra feature to all his smtp-servers. Outgoing email needs a reply-to adress in the header, that fits one of the mailboxes from the sender's domain. They explain it in http://wiki.goneo.de/doku.php?id=mailversand_phpas such:

Before: sendmail_path = /usr/local/sbin/sendmail -t -i
After: sendmail_path = /usr/local/sbin/sendmail -t -i -f mail@ihre-domain-bei-goneo.de

Now i can send emails via smtp-auth proxy to smtp-server of my provider by using Thunderbird directly. But if i send the same email out to SME, and from there to SMTP-Server at my ISP, it is rejected by the ISP's SMTP with "authentification-error".
If i disable smtp-auth, i get

82.XXX.XXX.XXX does not like recipient.
Remote host said: 553 5.7.1 <blah@blah.de>: Sender address rejected: not logged in
Giving up on 82.XXX.XXX.XXX

Provider's helpfile also says, the the smtp-authentication should not be secured. Plain username + password.

As a workaround i installed a small mercury mailserver for smtp-delivery. This works flawlessly SME->fixedIP->Mercury@windozeWS->ISP-SMTP. But this is no solution.

How can i get these 2 settings into SME, so i can at least figure out?

Go to email panel in server-manager and delegate the email server to your ISP. Fill the fields with your ISP SMTP address, username and password.

The problem is beyond that: Of course the smtp-server is delegated to isp with username/pw. But authentication (Server uses Plaintext/PW) does not work (as it does with any other smtp client or email-prog i tested so far).

To solve the problem, i first need a more extensive log-file just like this one from another smtp-client

Info::Connect smtp.provider.de:25
Recv::220 smtp1.provider.de ESMTP
Send::EHLO KISTE06

As I stated in the bug tracker, your ISP has introduced restrictions which make it impossible for you to run a mail server. Their service can only be used by individual/personal email. You will need to talk to them to get them to remove that restriction for you, or you will need to find a different ISP.

You can get more extensive logging by enabling debug with the smtp auth proxy in SME server. But I doubt that will help, because of the restriction the ISP has applied to the 'Mail From:' phase of the SMTP transaction.

Instructions to enable debug here:

You'll need to define more fully "does not work". Please do so in the bug tracker.
