Description
Address of the mail server via which the e-mails are sent.
The IP address can be specified absolutely or symbolically.
The following applies to symbolic names:
A valid name has 1 to 64 characters of which at least one
character must be a letter.
If one or more "." characters are used, the following constraint also
applies: A valid name has 1 to 3 characters behind the last "."; at
least one of these characters must be a letter.
A symbolic name can only be used if the Internet CP knows the
address of the Domain Name System (DNS). Make an appropriate

A maximum of 64 characters can be entered.
Specification of an address that is always inserted in the email as
sender address, if the sender specification (FROM parameter) is
empty in the header of the email.
This information is normally irrelevant for delivery of the mail. It is
simply information for the mail recipient. Since some mail servers
do not forward jobs if there is no sender information, it is advisable
to enter information here!
A maximum of 126 characters can be entered.
Note:
Remember that a default sender name must be specified if you
want a test mail to be initiated by special diagnostics.
