=head1 Description
|
| 22 |
|
| 23 |
mail-out.pl reads messages fed into the og2list outgoing queue and
|
| 24 |
sends them out via a locelly installed MTA's /usr/bin/sendmail
|
| 25 |
interface.
|
| 26 |
|
| 27 |
If the -d ("digest") switch is set, send multipart/digest messages to
|
| 28 |
those users that have digest delivery configured.
