SMTP mailing problems.
My site nsitlounge.com , hosted by amzweb.com has been back on and has been performing resonably well. The forum membership has crossed the 500 mark and I once again thank Cybertoad and other admins for the great time (its been nice overall
However, theres still a stingy problem

Our college is organising a cultural fest next month and we at nsitlounge.com will be handlig all the online affairs . This involves a Volunteer registraion form which sends and email to the admin team when some one registers to volunteer. This is a very important part of our automation process and we need the emailing ability of the website if the online registration is to be of any use.
New registrations at the forum dont even get a welcome email because of the same problem. However, I noticed that the clubhost.us (also hosted by amzweb.com) forum is able to send emails which means there is a way out of this problem.
Please help me out !!
