OT Multiple recipient email

[David Fletcher]

My email server went down a couple of weeks ago, so now I'm trying to get it 
configured again.

It's just about working, but there's a little problem that I never managed to 
find before.

The server is configured firstly as an outgoing mail relay using postfix with 
sasl to work as an authenticated smtp client. This appears to be working just 
fine.

At my email provider One and One, there is a mail box used to collect mail for 
multiple people, with forwards set up to direct mail for john at example.com, 
mary at example.com etc. to the same box.

This mail box is emptied by fetchmail running as a cron job, which passes 
messages to procmail for filtering and sorting.

Normally, this works.

AFAICT my problem is, if a single message is sent to multiple recipients 
@example.com, it goes into the One and One mail collection box as a single 
message with multiple recipients, gets collected by fetchmail as a single 
message, then gets dropped by procmail into the first matching local mail box 
it finds, so that only one of the recipients actually receives the message.

I can log into the One and One mail box with web mail, and sure enough it 
shows a single message with multiple recipients.

Is it possible to somehow tell fetchmail to make multiple copies of these 
messages before passing them on to procmail?

Or is this what's happening? See 
http://fetchmail.berlios.de/fetchmail-man.html
quote "Also, note that in multidrop mode duplicate mails are suppressed. A 
piece of mail is considered duplicate if it has the same message-ID as the 
message immediately preceding and more than one addressee. Such runs of 
messages may be generated when copies of a message addressed to multiple 
users are delivered to a multidrop box. "

I've been searching for a solution to this all morning, can't find it.

Can anybody help me please?
