Distribution List Recipients Receiving Message Twice

Hi

I am sending mail to a distribution list. Some recipients report that they are getting the mail message twice.

When I send the message to email address separately, none of the recipients get a second copy.

I thought it could be email forwarding setup at the recipients end, e.g. company.com has their email server setup to forward joe@company.com email to jerry@company.com and both names are in my distribution list, but some recipients getting double emails are the only recipient at their company/domain.

I have deleted and rebuilt my distribution list from scratch to ensure that there are no duplicates in it.

Any other ideas?

Thanks.

The people who are getting the double emails are not always from the same company. All of the addresses are external email addresses, i.e. not from my company.

Yes as I mentioned, when I send mail separately to each user, not using the distribution list, there is no double email.

This is a very strange one.

How many people in your distribution list?  More than 75 or so?

I'd be willing to hear it anyway...just in case...or for later use maybe.

Sorry there are 21 recipients. 8 of them get dups.

When split into two lists, list A has all duplicate receivers, and they still get duplicates. List B has all non-dups and they still get no dups.

One of the dup receivers is in another of my distribution lists and gets dups when I send to that dist. list too.

One user said that the second email comes about 2 minutes after the first. Is there some kind of time out or somthing in Exchange that would cause it to resend an email?
