Local domain name without a host name.

This is appended (with an @-sign) to any specified recipients which do not include an @-sign, so that each RCPT TO address is fully qualified.
(Some configurations of sendmail require this.)

Don't bother to set this unless you have get an error like:
Sending failed; 501 <someone>: recipient address must contain a domain.
