SMTP-Gateway 5.0
To create a new group of addresses:
1. Create section [smtpgw.group:group_name] in the configuration
file.
2. In the Senders and Recipients fields, specify sender and recipient
addresses (masks of addresses) separated with commas.
To define masks, use the "*" and "?" symbols.
If you do not define the Recipients OR Senders pa-
rameters, the default value will be "
*@*"
It is required to set at least one of parameters Senders
or Recipients.
If you added other groups to the configuration file, the application will process
messages from these groups as follows:
1. The application first compares the message address(es) with
addresses in the groups created by the administrator. If the
recipient/senders addresses pair is found in a specific group, the
rules for this group will be applied to the message.
If the sender/recipient address matches the addresses of several
groups, the application will use the rules for the first of these groups.
2. If the message addresses do not match any group, created by the
administrator, the message will be processed according to the rules
described in the policy group.
If a message has several recipients that belong to different groups, vir-
tual copies of the initial message will be created to match the number of
such groups. Each copy will be processed individually according to the
rules specified by the particular group.

Gateway with a received email message.
