Avoiding duplicate/multiple redirected email messages.

[ArshadM]

Dear Sir,

I have Qmail installed in Control Panel Plesk 9 and Operating System Debian 4.0. I desire to know how to get only one copy of message instead of duplicate/multiple messages in a scenario such as the following redirected emails :-

[email protected] redirect to [email protected]
[email protected] redirect to [email protected]
[email protected] redirect to [email protected]


If someone send email to [email protected] with CC to [email protected] & [email protected] the same email message at [email protected] is received three times.

Is there any way to restrict to receive only one copy of the same message even if redirected from different accounts. Previously in sendmail the solution was available and all email accounts used to get only copy of the messages and multiple copies were able to avoid.

Regards.

Arshad.
