syncnews - synchronize IMAP news mailboxes with active file
syncnews [ -C config-file ] active-file
Syncnews compares the list of IMAP news mailboxes with the news active file. News mailboxes which are not listed in the active file are removed. Newsgroups listed in the active file but not in the IMAP mailboxes file have IMAP mailboxes created.
A newsgroup must have a status of ``y'', ``m'', or ``n'' to be considered listed in the active file.
Syncnews reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.
-C config-file
Read configuration options from config-file.
