In VPOP3 a 'group' is mainly an administrative feature. If you only wish to have a list of email addresses to send messages to under one address, you should use the 'List' feature instead. The main function of Groups is to let you set certain user attributes for a whole group of users at once.
However, you can email to a group by sending a message to <group.name>@<your.domain> if you wish. Note that only internal users can send emails to groups this way, incoming messages will be treated as if the recipient was unknown. (With lists, you can choose whether external users can send to the list or not)
To manage the groups go to
Settings → Groups in the VPOP3 settings.
To add a new group, press
New above the table, then enter the group name.
The group name must contain only alphanumeric characters, '.', '-' or '_' characters. A group name cannot be the same as a user name or a list name. This is because you can use the group name in an email address.
To delete a group, select it in the table, and press the
Delete button above the table.
To edit a group, you can just use the controls in the group table.
Some of the controls are three-state checkboxes. In these cases, if the checkbox is checked as normal, then all members in the group will be made to have this setting set; if the checkbox is clear, then all members will be made to have this setting unset, and if the checkbox is greyed, then all members in the group can have their own individual setting (that particular setting is not affected by the group configuration).
The settings are described below:
