bounced messages and VERP ??

hi,
I am using mailman with postfix. While testing mailman I created a list with two address. Both had same domain say "mydomain.com".
When all was working fine, mailman/postfix used to copy a single mail to both the users. I had a problem with one of the IDs and the mail destined to it bounced few times. Later I fixed it, but found that now mailman (or postfix) has started copying two separate mails to both the users?
What has changed? Is this a problem ? I may add more than 3000 users from the same domain and I don't want each user to get a separate copy!
Please help/advice??

The subject line of your post implies that you may have turned on Mailman's personalization to this list so that the return path is VERP'ed by Maiilman.
If that is the case then each subscriber will by definition be sent a unique message by Mailman for each posting distributed.
You would get a similar effect if, for instance, the MTA were generating VERP'ed messages from a single original message passed to it by Mailman but addressed to multiple addresses.
Could this be why you are seeing what you are seeing?
Please help/advice??

thanks
But I haven't any change. I am running postfix as it was. I observed the thing when I fixed the problem with the ID and posted a test message.
I wrote VERP because, I remember such a setting exists. But in fact I haven't changed anything.
Is this happening because few message to that ID had bounced and mailman wants to be careful while sending mail to that ID so that in case it bounces it will be easy to find the recipient address and increase his bounce score ??

Sorry
I think I need a answer of a single question: How do I make sure that Mailman is not VERPing mails? And if I find that it is VERPing mails then how do I turn it OFF ??
Do I need to re-configure my list? What is the parameter in sitelist.cfg file which I need to change for this??
TIA

Go to the admin web page for your list. Go to the "Non-digest

Should Mailman personalize each non-digest delivery? This is
often useful for announce-only lists, but read the details
section for a discussion of important performance issues.
(Details for personalize)
Make sure that the radio button in the field to the right of this
description is set to "No". If not, change it to "No", and then click on the "Submit Your Changes" button at the bottom of the screen.

VERP'ing is done for different types of mail (regular postings, password reminders etc) depending on what the config variable settings are.
Check the personalization settings for the list concerned which will affect normal postings if allowed by the config variables..
Definitively, you can just check what your outbound MTA is logging to determine what it is receiving from Mailman. The 'To' line for an oubound mail should tell you what you need to know.
