I just noticed this report.  Is there a function in elisp that does
downcase in the C locale?  For this use, we only care about ASCII, so a
'tr A-Z a-z' would work.  Do smtpmail.el have to implement a
'downcase-ascii' function itself?

Chong Yidong has fixed some similar issues in smtpmail.el using
with-case-table / ascii-case-table, see
http://thread.gmane.org/gmane.emacs.gnus.general/64489/focus=64496

See <http://thread.gmane.org/gmane.emacs.devel/68859> for the quite
long discussion about this problem (Subject: ... Locale Dependent
Downcasing in smtpmail).  Oh, know I notice that
<yazicivo@ttnet.net.tr> reported this problem, so I'd guess it has
been fixed by Chong Yidong's change.

Bye, Reiner.

I'm happy to hear that it has already been fixed.  I didn't notice any
follow-ups on the post to emacs-pretest, that's why I asked again.

Thanks,

You can switch to the standard case table for this.
