bulletin <subcommand>
The bulletin command establishes how JNOS treats incoming bulletins based on their R: line headers. These commands are available when JNOS was compiled with #define RLINE, and are highly recommended for BBS operations. While many defaults are OFF for historical reasons, I (note: author unknown) think most BBS operators will want to turn these features ON!
bulletin check [on | OFF] Displays or sets a flag indicating bulletin forwarding is to be optimized. If <ON>, an incoming bulletin's R: lines are scanned for BBSes to which we forward. If any are found, the bulletin is marked as having already been forwarded to that BBS. When invoked with no options, the list of BBSes to which we forward is also displayed. Note: only the first NUMFWDBBS (currently 8) BBSes in forward.bbs are checked in the R: lines, hence the most active BBSes should occur first in forward.bbs.
bulletin date [on | OFF] Displays or sets whether the date associated with a message is the originate date (if ON), or the date received (if OFF). The originate date is obtained from the last R: line, and should yield better operation of the bulletin expire mechanism. See also 'bulletin holdold'.
bulletin holdold #days Displays or sets the number of days since message origination, above which an incoming bulletin is placed into a hold state. A held bulletin is visible only to the sysop, and has a "X-BBS-Hold: Age" header added. This feature only works when 'bulletin date ON' is in effect.
bulletin loophold [<count>] Default: 2 Displays or sets a counter which, if exceeded by the number of times our call appears in a message's R: line headers, causes the message to be Held to avoid a message-forwarding loop. A held message is visible only to the sysop, and has a "X-BBS-Hold: Loop" header added.
bulletin return [on | OFF] Displays or sets how a message's return address is obtained. If ON, the return address is obtained from the last R: header line when available. If OFF, sender%forwarding.bbs@mycall is used.
Note that for the mailbox SR (send-reply) command to work, the system's rewrite file must be capable of handling the '%' symbol. A recommended rewrite rule is:
*%*@YOURCALL* $1@$2 r
