Re: Mail error 451 warning messages



@andrew:
sbs-server send mails over smart-host to the destination server. The
Destination Server use qmail. Yes, the message is generated by qmail, but the
Problem withe the bar LF is generated at the sbs-server.

@Merv:
antivirus off takes not effect.

the MS-KB-article (following the tipps in
http://groups.google.com/group/microsoft.public.windows.serv... ): there was
exist a smtp-connector. This SMTP-Connector send to the smart-host and make
second connector?

the link http://blogs.technet.com/sbs/archive/2006/03/13/421943.aspx
describe the problem correct, but the workaround doesnt work, i have set the
redirection in the user-settings in exchange (not in outlook) and the problem
is the same.

but now i give up. the subject of the error mails say enough so that I know
the problem on the server.

if i found a workaround, i post it here.

thanks,

jens

Hallo,

i have a problem with send the warning-mails from sbs 2003r2.

the destination mail-server answer:
SMTP error from remote server after transfer of mail text:
host xxxxxx:
451 See http://pobox.com/~djb/docs/smtplf.html.

That is not an SBS message but a message generated by the Qmail MTA
package. This implies you are sending these off-site - if so, how are
you sending the mails - through a smart host?

If the smart host is running the Qmail package, then this may be the
issue, as Qmail is very funny about these, and when our company used
it we got a lot of bounces because of this - mainly from automatic
scripts such as SBS warnings etc.

You can test the running of Qmail by telnetting to the external SMTP
server on port 25, you will get a banner response like:

220 server.domain.com ESMTP

If you enter in help and press enter you should be given the Qmail or
the NetQmail homepage.

Thanks.
Andrew.
