Why adding a contact form? If a postmaster really does his/her job and scans the logs, finds your assistance info and enters the website, don't you think the same admin is also able to write a mail to you (postmaster@...)? OT: Concerning captchas: Yes, I hate them a lot. I have many problems with my eyes. And sites working with captchas are often a stopper for me. Left eye nearly blind, right eye with 60-70% and yes, color blind, too. So captchas are really a cool idea *ironic* IMO: Adding the page is really nice and should give a remote postmaster enough information to either fix his/her setup or contact you (postmaster@).
