multiple same e-mails

[Joe Rest <jo...@gmail.com>]

Hello there!

I have got apache james 2.3.2 and this situation, please help.

In our company we have got 2 types of mails:

user mails - like joe.rest@example.com , accounts created on localhost with
remote manager tool (4555)
group mails (virtual) - like employs@example.com, finance@example.com,
newcarrier@example.com etc... for group of people, mail in real doesnt
exist only send mail to configured real user accounts like joe@localhost,
lisa@localhost ...


in config.xml:

...
<mailet match="RecipientIsRegex=.*(?i)rest@example.com" class="Forward">
            <forwardTo>joe@localhost</forwardTo>
            <debug> true </debug>
</mailet>
...
<mailet match="RecipientIsRegex=.*(?i)finance@example.com"
class="ToProcessor">
            <processor> financeProc </processor>
</mailet>

<processor name="financeProc">


         <mailet match="HasMailAttributeWithValueRegex=header, (?i)
rest@example.com" class="Forward">
                  <forwardTo> joe@localhost </forwardTo>
                  <passThrough> true </passThrough>
                  <debug> true </debug>
         </mailet>

<mailet match="HasMailAttributeWithValueRegex=header, (?i)moore@example.com"
class="Forward">
                  <forwardTo> lisa@localhost </forwardTo>
                  <passThrough> true </passThrough>
                  <debug> true </debug>
         </mailet>

</processor>
....

Problem is when someone send e-mail to me and to the group in which I am. I
get that e-mail 2 times.

It's logical i made it this way, but is it possible to avoid duplicite or
more times sent e-mail on the server side ? Custom mailet or something ?

Thanks in advance,
joe
