1836This will be used when doing followups and posts.

1838This is primarily useful in mail groups that represent closed

1841parameter ensures that the mail only goes to the mailing list itself,
1842it means that members won't receive two copies of your followups.

1846`fa.4ad-l'. This is a real newsgroup, but the server has gotten the

1848is therefore impossible--you have to send mail to the mailing list
