I think I asked this before, but I can't remember if an answer came over...

In UK-sendmail 1.4a, there was a rule that said :-

| R$+ at $+               $1@$2                   " at " -> "@" for RFC 822

The problem is that sendmail/lib/usr/ (pathname in WORLD ORDER!) seems
to be no respecter of spaces and although the above line does work
as intended; translating addresses like "user at site" into "user@site";
it also has the side effect of translating "user@AT.site" (Austria)
into "user@@.site" (nowhere much use!).

In UK-Sendmail 2.1, an attempt to get round this is to escape the spaces:-

| R$+\ at\ $+               $1@$2                   " at " -> "@" for RFC 822

Although this prevents the "AT" domain getting translated it also prevents
the "user at site" translation from occuring, as far as I can see.

Obviously the same result could be obtained by deleting the rule!
SO did someone get it working, perhaps on a different sendmail?

Should anyone worry (I assume that the " at " use is uncommon these days)?

This is all with sunos 4.0.3's own sendmail.
Many thanks for any (possibly repeated) attention you are giving this one.
