iftoss - Convert Fidonet FTN packets to RFC-822 and RFC-1036 mail/news.
iftoss [-h] [-N] [-x verbosity] [-I file]
Iftoss converts Fidonet netmail packets into RFC-822 internet mail or
RFC-1036 Usenet News. It expects a non-arcmail packet on stdin and
passes converted mail messages and/or generated newsbatch to sendmail
and/or rnews. If you specify -N, resultant messages/newsbatches will
go to the directory "/tmp/ifmail" instead of being fed to
Ifmail and iftoss programs try to preserve as much information as
possible in "X-FTN-..." headers and "^ARFC-..." kludges, and restore
messages more or less accurately to their original form when double-
If you make a system mail alias file accessible to the iftoss program,
it makes attempt to "backward resolve" the "from" addresses, that is,
if the originating address of the FidoNet message matches the right
side of some mail alias, the "Reply-To:" header of the generated
mail/news message will contain "firstname.lastname@example.org" address.
Message IDs are converted as follows: "^AMSGID: <address> <hexnum>" is
converted to "<decimalnum>@<address>". If there was no MSGID in the
fidonet message, messageid of the form <creation-time>@<from-address>
is generated, so that when a single message is gatewayed in several
distinct places, it will have the same messageid anyway (for some
(little) risk of having two different messages with the same
messageid). RFC822 Message-IDs are converted back when they can be,
otherwise the messageid "<local>@<domain>" is converted to "^AMSGID
<domain> crc32(<local>)". When an RFC message is split, unique MSGIDs
are generated for all parts after the first one. In any case, the
original "Message-ID:" header is preserved in the "^ARFC-Message-ID:"
kludge and used if the message comes back to usenet on some (other)

Set the debug verbosity. verbosity may be a number from 0 to 32 to set
’on’ bits from 1 to number, or a string of letters where ’a’ = bit 1,
’b’ = bit 2, etc. up to bit 26.
