Of course you know better what I know.

I linked that.

There is no such thing as legacy escaping. Please show us a binkd version from the 90s that uses \## instead of \x##. I don't think there is one. AFAIK it was always \x##.

Nope, it's a bug in Mystic.

Of course you don't (and know better). Maybe your users do care though.

So you say that binkp should implement a workaround, because some Mystic versions don't understand a "\x20" specified by a > 15 years old FTS?

Argus indeed expects \##. But it's not "original binkp".

FSP-1011 had an error and "some mailers have implemented that method". For that reason FTS-1026 states that "any mailer SHOULD decode \20 into space in file names for compatibility purposes". FTS-1026 did not update/change \20 to \x20, but added \20 as an alternative escaping method for non-

binkd also added a workaround for non-compliant mailers (but only one way).
