multihome -- sendmail multihome aliasing mailer

Synopsis

multihome [-t | -d] recipient

Description

The multihome mailer program routes mail addressed to users in virtual domains to the correct physical users on the system. It does this by modifying the recipient list and resubmitting the message to sendmail(1M).

The mail message to be routed is expected to be on the standard input.

mailintro also supports aliasing for each virtual domain.

Options

-t: Address test mode. This outputs a new recipient list after performing aliasing and user mapping.
-d: Debug mode. Similar to -t, but prints addresses at each stage of the lookup.

NOTE: When using these options, mailintro does not process a message from stdin.

Files

/var/internet/ip/127.0.0.1/virtusers
Virtual user mapping file. Maps virtual users in each domain to physical users. This file is normally edited by the multihome(1M) utility. Syntax for each line in the file is:
```
   virtuserid@virtdomain realuserid
```
/var/internet/ip/127.0.0.1/virtusers.db
This dbm database file contains a hash table reflecting the virtusers text file. This file is built automatically when the multihome(1M) utility is used to update this file.
/var/internet/ip/127.0.0.1/mail/virtdomains
A local cache of the valid virtual domains. This file maps virtual domains to IP addresses. This file is updated automatically by the multihome(1M) utility.
Syntax for each line in the file is:
```
   virtual_domain_name virtual_IP_address
```
For example: machine.com 123.456.789.123.
/var/internet/ip/127.0.0.1/mail/virtdomains.db
This dbm database file contains a hash table reflecting the virtdomains file. This file is built automatically when the multihome(1M) utility is used to update this file.
/var/internet/ip/x.x.x.x/mail/mail.aliases
One of these files can exist for each virtual domain. These files contain the aliasing information for each virtual domain. These files are normally updated with the multihome(1M) utility.
Syntax for each line in the file is:
```
   alias_name: comma_separated_alias_entries
```
For example: alias1: user1, user2.
Note that these alias files support :include: in the same manner as standard sendmail alias files.
/var/internet/ip/x.x.x.x/mail/mail.aliases.db
