#57 sm returning success page on 501 fail

[Jim Morrison]

Soupermail appears to be returning the gotosuccess
page, despite the mail not being accepted by Sendmail,
with a 501 (Domain does not exist)

From debug log..

<SNIP>
MIME::Lite::SMTP=GLOB(0x84e0428)>>> MAIL
FROM:<foo@domaindoesnotexist.com>
MIME::Lite::SMTP=GLOB(0x84e0428)<<< 501 5.1.8
<foo@domaindoesnotexist.com>... Domain of sender
address foo@domaindoesnotexist.com does not exist
SMTP MAIL command failed:
5.1.8 <foo@domaindoesnotexist.com>... Domain of
sender address foo@domaindoesnotexist.com does not
exist

at (eval 33) line 411
</SNIP>

Otherwise is working great ;-)
