One Mailbox cannot sending Mails

[Stefan Becker]

Hi,

i have one Mailbox on my server, which i cannot sending mails. I tested it with Outlook and Horde.

For Example, i see this error at the Maillog:

Jul 14 22:12:13 gaius postfix/cleanup[12194]: 2F653402A6: milter-reject: END-OF-MESSAGE from localhost[127.0.0.1]: 5.7.0 The message could not be sent. You are not allowed to use sendmail utility.; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<gaius.stefanshome.com>

I delete this Mailbox, but after a time, i have the same problem again. On the Plesk Webinterface there is no problem logging with the outgoing spam protection.

Have anyone an idea?

Stefan

This message should appear neither when using Outlook, nor Horde (since they use SMTP). This means that either you're looking at the wrong log line, or your mail subsystem configuration is slightly wrong.

But only with one Mailbox? All others work fine...
