1.0.2 not redirecting or sending

Hi, I read through all the posts I could find that hinted at a similar problem, including one of mine from long ago, but I'm still stuck. Apologies if I missed one with an answer... I also set up a ticket with the host but I feel you all can help better.

Page in question is here contactgch.php

Globals is currently at standard re email server, i.e. blank.

I'm getting these warnings (need to view source to see them as they get covered up):

Warning: mail() [function.mail]: Failed to connect to mailserver at 192.168.1.67 port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\Domains\greenwichcolonhydrotherapy.com\wwwroot\ContactForm_GMC\WA_Universal_Email\mail_PHP.php on line 254

Warning: Cannot modify header information - headers already sent by (output started at C:\Domains\greenwichcolonhydrotherapy.com\wwwroot\ContactForm_GMC\WA_Universal_Email\mail_PHP.php:254) in C:\Domains\greenwichcolonhydrotherapy.com\wwwroot\ContactForm_GMC\contactgch.php on line 35

I did find one whitespace space and removed it but it didn't change anything.

There was a thread with these two lines mentioned but the dude just said the host fixed it...

The validation works well or seems to.

Can you see anything my still noobie brain is missing? Should I wait to see what the host says?
The site is on accuwebhosting.com on a Windows starter package that is supposed to support PHP 4 and 5 if that helps.

Thank you!
