I'm having an strange problem with my qmail servers, some times our users get messages returned from remote servers that they haven't sent to (there is no virus in their systems, some of them are unix hosts).
The headers indicate that the message is sent directly from the mail server but the destination address is not copied in the email, for example I got this returned mail but the original sender didn't sent message to [EMAIL PROTECTED] (neither he knows this guy) and there is no forward or virus in his PC (it's a unix machine)
Hi. This is the qmail-send program at ms03.mydomain.
I'm afraid I wasn't able to deliver your message to the following
addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<[EMAIL PROTECTED]>:
212.227.126.147 does not like recipient.
Remote host said: 550 Unknown local part jmcClureea in
<[EMAIL PROTECTED]>
Giving up on 212.227.126.147.
Does anybody have any idea about what could be wrong?
The environment:
- Operating System: Solaris 7
- qmail with qmail-ldap patch
Thanks in advance,
