messages from the tacos mailing list, as the subject header doesn't
include a common entry like most mailing lists on the internet, such

[TACOS] Re: International Space Station in cross-band repeater mode!!

sort the incoming mail according to the subject header, and then also
to differentiate the Tacos/Amrad mail from the other junk mail that
arrives in the mailboxes ?

Just a thought!
