Hello,

maybe i found a bug in courier.

courier crash's when a E-Mail address contains "–" (EN DASH)

Kernel log:
traps: courieresmtp[36082] general protection

mail.log:
courieresmtp: Crashed child process 41684, while delivering to DO<96>MAIN.TLD

When i try to send a mail to DO–MAIN.TLD via thunderbird (smtp server is the same) or something else Server report: No such domain (replace DO–MAIN.TLD with a real domain containing normal "-")

tested with:

cat /some/mail/content | sendmail user@do(echo -e "\0\x96"| tr -d "\0")main.tld

is this a bug from courier? debian? maildrop?


kind regards
Philipp
