External Emails to users going to distribution group but can't figure out why

This has just started happening and trying to figure out why - If an external email comes in to usera then gets sent to usera but also to a distribution group.  I have checked and the users do not have autoforwards, rules or forwards in AD that would be causing the problem.

We have GFI Mailessentials 2010 which was playing up

So in message tracking shows
SMTP: Message Submitted to Advanced Queuing
SMTP: Started Message Submission to Advanced Queue
SMTP: Message Submitted to Categorizer
SMTP: Message Queued for Local Delivery
SMTP: Message delivered Locally to usera@domain
SMTP Store Driver: Message Delivered Locall to Store to usera@domain
SMTP: Message Submitted to Advanced Queuing
SMTP: Started Message Submission to Advanced Queue
SMTP: Message Submitted to Categorizer
SMTP: Message Categorized and Queued for Routing
SMTP: Message Categorized and Queued for Routing
SMTP: Message Queued for Local Delivery
SMTP: Message Delivered Locally to group@domain
SMTP Store Driver: Message Delivered Locally to Store to group@domain
SMTP: Message Delivered Locally to multiple recipients
SMTP Store Driver: Message Delivered Locally to Store to userongroupa@domain
SMTP Store Driver: Message Delivered Locally to Store to userongroupb@domain
SMTP Store Driver: Message Delivered Locally to Store to userongroupb@domain

This seems to be happening to majority of users and I am stumped.  I have upgraded the GFI to latest version released today and server has been restarted - this just started happening this week and resulting in everybody on the group getting tons of emails and mails that should not be forwarded on

Running Exchange 2003

Any ideas?

I thought I had updated this post - it turns out that the problem was down to Mail Monitoring settings in GFI.  I stoppeed GFI and resolved so went through all the different features till found something pointing at group@domain

Thanks for the comments

Try disabling GFI and see.
Also, is this issue just specific on one user?
if so, I would suggest you to check the targetaddress attribute too through adsiedit.

Good luck.

Is the Mailbox Store set to journal to the distribution group?

Can try disabling GFI as

SMTP Store Driver: Message Delivered Locall to Store to usera@domain
SMTP: Message Submitted to Advanced Queuing

suggests that something is forwarding emails to the group. is there a journal mailbox that's forwarding emails to this group ?

There appears to be a journal setup but to archive@domain not group@domain so so also see it going to there in the message tracking - I have checked there is no forward or rules on the archive account to forward to distribution group

Missed this before -

SMTP: Message Submitted to Categorizer
SMTP: Message Categorized and Queued for Routing
SMTP: Message Categorized and Queued for Routing

Any message categories set up ? as, it shouldn't say 'Message Categorized and Queued for Routing' if there were no category based route set up

Can you send a test message to usera from intermally account and external account and see if this happens.

Can you try stopping GFI and then sending emails and see if they get delivered to designated users mailbox ?
