sendmail and Exchange Email Accounts

[curtiss]

About a year or so ago, we moved all of our email accounts off of our hosted web server, and onto our own in-house Exchange server. At that time, we stopped receiving all emails that were sent through webforms.

I thought it was because sendmail had been disabled when we moved our MX Records. However, I just discovered today that the emails had not been getting bounced, or sent to a blackhole in cyberspace. They had, in fact, been getting sent to the original "catchall" email address we had set up on our hosted web server.

I spoke to customer support today, to see if there was anything we could do about it. Unfortunately, their only response was "sendmail/formmail can only send mail to POP3 accounts". They offered no helpful suggestions on the matter.

Does anyone here have any suggestions on how I can get my web-forms to send email to our Exchange accounts?

I am getting ready to switch our site over to a CMS, and the CMS relies heavily upon web-based forms to communicate with us (rather than showing our email addresses, all "contact" type stuff is handled through contact forms). I really would like to get our web forms working properly again, but have not figured anything out, yet.

how does sendmail know if it is a pop account or not?

my xxx@xxx.com entered on a sendmail form is the same no matter what the receiving server is.

i know at work, i received thousands of form submissions with no issue - and it is an exchange server.

That's kind of what I was wondering. The thing that really got me wondering about that whole thing was, I used my Yahoo mail account as the address that a form sends mail to, and it went through flawlessly. AFAIK, Yahoo mail accounts are not POP3.

I would really like to find some sort of solution to this problem, as I think my host is just kind of jerking me around, as they don't understand what the problem is themselves. If I can find a solution myself, I can either implement it myself, or I can request that the host implement the fix.

I don't get it either. sendmail does not know what the recieving server is. I think it has to be another issue. Maybe the MX-record is not found for your exchange server. No idea.

I also don't understand why there is a catch-all on your hosted server and then there is Exchange "in house"? How is this connected. I mean, it sounds like you send your forms to an e-mail address that is hosted somewhere else - not on your exchange server.
