Package: libc-client2007
Version: 7:2007~dfsg-1
Severity: normal
certain SMTP "smarthost" servers (incl. some maintained by yahoo) give a
non-rfc-compliant response to AUTH LOGIN (RFC2554,sec 4,"Discussion")
(the message after '235' is not valid base-64 code)
which makes them hard to send mail through. this patch causes the garbage
to be ignored, resulting in a successful session rather than a failed one.
I have prepared a pathc which "fixes" c-client so that interaction with
yahoo is successfull.
