When specifying SMTP host as an IP address in the php3.ini file (e.g. SMTP=192.168.101.1),
the gethostbyname() call performed by sendmail.c times out, resulting in very poor performance.

A quick hack: If MailHost starts with a numeric character, do not perform the gethostbyname() call 
(BTW: The results do not appear to be used anyway!)
