sendmail relay problem: dsn=5.0.0, stat=Service unavailable

Postby mwiertz » Tue Feb 19, 2008 9:37 am

Hi,

I'm experiencing the following problem since a few days:

Code: Select all

Feb 19 14:27:32 donkey sm-mta[8065]: m1JDRU3F008065: from=<max@maxwiertz.nl>, size=957, class=0, nrcpts=1, msgid=<190585.111203427649176.JavaMail.root@donkey>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1]
Feb 19 14:27:33 donkey sm-mta[8071]: m1JDRU3F008065: to=<someone@somehost.com>, delay=00:00:02, xdelay=00:00:01, mailer=relay, pri=120957, relay=outbound.mailhop.org. [63.208.196.178], dsn=5.0.0, stat=Service unavailable
Feb 19 14:27:33 donkey sm-mta[8071]: m1JDRU3F008065: m1JDRX3F008071: DSN: Service unavailable


I am using sendmail as MTA and configured a forwarder like described on the dyndns.com site:

In my sendmail.mc file I added the following:

Code: Select all

FEATURE(authinfo, `hash -o /etc/mail/auth/client-info')dnl
define(`SMART_HOST', `outbound.mailhop.org')dnl


And the file client-info contains the credentials to be used.

Somehow something blocks my access to the mailserver. I trying and searching the web for about two days already by now, but I cannot figure out what causes this problem.

I even tried another relay server, and it still does not work. Further I can reach the server when trying via telnet (telnet outbound.mailhop.org 25).

I even installed the os and the whole scalix and sendmail stuff from scratch.

Please help! :(
