Hello everyone,
Years ago I made a suggestion here about this, now that I am a little
less ignorant in C I dared with the patches below, they add a '-e'
option to mail(1) to pass a Content-Transfer-Encoding on the command
line. First you convert the text in "message.txt" to quoted-printable
or base64 (a simple shell script would do the job) and then you're able
to send international text doing this:
$ mail -s Hello -e quoted-printable recipi...@example.com < message.txt
