Subject: [PATCH] send-email: extend sanitize_address_rfc822 to do rfc2047 quoting
Message-ID: <11840869641759-git-send-email-ukleinek@informatik.uni-freiburg.de>

Without this patch I'm not able to properly send emails as I have a
non-ascii character in my name.

As I'm not a perl profi, someone wants to check this code.

Actually this series is a test, as it is sended with the patched send-email.

I hope it works :-)

Uwe
