Log Message:
Use nearest-zone matching for source FTN address when replying to netmail

Rather than only matching exact zone numbers as a final "nearest" address search, use a "nearest zone" matching algorithm ("nearest" being the most mathematically near). This way, replying to netmail from a zone 2 address
would always match a zone 1 source address, regardless of how many othernet addresses are configured and which order they are configured in SCFG.

Hi Rob,

Today you probably get away with this algorithm. But that is a matter of luck, not of how the algorithm works.

In the past when Fidonet had 6 zones and for instance you had a node number in Zone 1 and in an othernet Zone 8, and replied to someone in Zone 5 or 6, you would have replied from your Zone 8 othernet address... :-(

So if someone decides to create an othernet Zone 5 or 6, which is a bad idea, but they could, because the numbers are no longer used, your nearest-zone matching would cause netmail issues...

Bye, Wilfred.

It's just a default address selection algo. The user can always choose a different/more-correct source address, if the system has one.

Ok, didn't understand that... ;)
