We have installed Email Server using Fetchmail & Sendmail.

We have some users are at Office and Some email account are roaming. We have configured Catchall Account in fetchmail which basically download message s and sendmail distribute it as per address mapping in Virtuser of sendmail . For user which are not present in at Local Server got forwarded to Nonbranchuser account.

Basically Nonbranchuser account is created for Local user can send mails to roaming account using fetchmail.

But What happen as i said above What ever mails downloaded and user not found on local Server is also get forwarded into nonbranchuser account are also get forwarded to roaming account and hence they are getting Repeated email

So Please give me your valueable suggestion on this !
