Why won't FMP5.5 Unltd. send out mail anymore?

[Silvia]

I have a web shop. Once the customer has confirmed his/her order it is supposed to send it as a mail to the customer and the shopholders.

It used to work fine, but then the mailserver here where I work was replaced by a new one, and after that it's not working anymore. I changed the mailhost IP adress in the mailform code (in the html page) to the IP of the new mailserver but it still isn't working. Is there anything else I could check? What could be wrong??!

This is the mailform code:

<FORM METHOD="POST" ACTION="FMPro" NAME="checkoutform">

<INPUT TYPE="hidden" NAME="-db" VALUE="Orders.FP5">

<INPUT TYPE="hidden" NAME="-format" VALUE="thanks.htm">

<INPUT TYPE="hidden" NAME="-error" VALUE="checkout.htm">

<INPUT TYPE="hidden" NAME="-lay" VALUE="CGI">

<INPUT TYPE="hidden" NAME="-token" VALUE="[FMP-currenttoken]">

<INPUT TYPE="hidden" NAME="-recid" VALUE="[FMP-currenttoken]">

<INPUT TYPE="hidden" NAME="Order ID" VALUE="[FMP-currenttoken]">

<INPUT TYPE="hidden" NAME="-edit" VALUE="">

<INPUT TYPE="hidden" NAME="-mailhost" VALUE="ipadress">

<INPUT TYPE="hidden" NAME="-mailfrom" ALUE="[email protected]">

<INPUT TYPE="hidden" NAME="-mailcc" VALUE="[email protected]

<INPUT TYPE="hidden" NAME="-mailbcc" VALUE="[email protected]

<INPUT TYPE="hidden" NAME="-mailto" VALUE="[FMP-field:Customers::Email]">

<INPUT TYPE="hidden" NAME="-mailsub" VALUE="KB Design Bestilling">

<INPUT TYPE="hidden" NAME="-mailformat" VALUE="emailorder.txt"></FORM>

Any help really appreciated! THANKS!!

Hi, Silvia! I wouldn't recommend pulling your hair out over code. It's probably the new mail server since everything was working fine before.

The new mail server may be interpreting your FMP connection as a SPAM attempt and not permitting it to go through. Check w/your mail administrator and make sure your FMP server IP address is on the "approved" list (or equivalent).
