Triplicate emails sent?

[Ashley Aitken]

Howdy All,

I am using MacOSX Server 10.4.x as our mail server.  We use IMAP and  
Mail.app as the client.

I think something may be wrong with the mail server set-up because

1. A colleague has just indicated that he get each of my emails three  
(3) times.  Which is strange because when I send them to myself on  
another email system I don't get triplicates and other people have  
not said anything about this to me (although they may just be  
ignoring it or thinking I am pushy ;-)

This colleague runs Windows and uses a third-party company (not an  
ISP) as their mail/domain server.

2. I get an automated bound message warning email every day from a  
mailing list I am on (but it says if I get the message it probably  
means the mail system is fixed).  I have registered with my .Mac  
email address but that is forwarded to my normal email address on my  
mail server.

I only get this bounce for one mailing list (Frontbase) although I am  
on many more.

Howver, I also sometimes receive duplicate messages from some of the  
mailing lists I am subscribed to (particularly some of the Omnigroup  
one's Macosx-talk I think, but also another Australian mailing list).

I should also point out that my mail server does not have a proper  
reverse DNS entry for the domains that I post/receive from (neither  
is correct) since I don't have control over that.  I am not sure if  
that would be causing the problem but I wonder if it will make some  
system label my email as spam?

Any help or suggestions would be most appreciated.

Cheers,
Ashley.
