1. Introduction

Every Administrator who has tried to receive e-mail, for more then one recipient, through a single mailbox from the provider, knows the problems about multi-mail-drop and mail-loops. After reading tons of discriptions about envelope and header addressing,there is still no real solution in sight.

For example, you have registered a domain with a provider and you have a mailbox with that provider, in which all mail for this domain comes in. You have set up Sendmail and Fetchmail to receive mail from the mailbox and deliver it to the local mailboxes.

Everything works fine till the first user wants to receive mail from a mailing list. When this type of mail comes in, Sendmail reads the address of the mail list within the "To:" header and sends the mail back to mail list. From the list, the mail is sent to all recipients again and to us. This type of mail will loop 20 or 30 times before detected by the administrator and the loop is stopped.

To avoid such loops for more than one recipient,I have written this mail filter. The mail filter searches for a specified domainpart in the e-mail addresses and replaces the original "To:" line with the mail addresses that fit the domain. The filter also searches for matching envelope addresses and adds the first matching found to the "To:" line.
