Well, I think a reading of RFC822 clearly indicates that mixed case is
allowed - it even gives an example of the "From:" header to show this.

My opinion is that MailTools (Header.pm) is as unreliable in this respect as
is its definition of an acronym being a word not containing a vowel (eg
Radar, Sonar, Laser, Eprom...)

In fact it's hard to even imagine an acronym which does not contain a vowel,
since an acronym is an abbreviation which can be pronounced.   That gets hard
if you have no vowels.

Antony.

Does that make me an agnostic atheist if I do not believe there is no God?
