The title is vague sorry. Basically we have a VPS with ColdFusion and use cfmail to handle contact forms on client websites. Under most circumstances our clients will have their own exchange server but we will control the DNS though HMS. In this particular case, the client has an exchange sever but also controls the DNS and routes all email through postini.

For some reason this particular client site is not sending email at all. No matter what email I point it to.
A sample cfmail would look like this:



Pretty much as basic as it gets. the CF Mail logs show it as being sent however they never show up. Not even to a bulk mail folder.

We have tried white listing the IP in exchange, setting up a noreply@ email and white listing that. I have also tried using cfmail to connect directly to their exchange server. That only produces an error that reads... Could not connect to SMTP host: mail.domain.com, port: 25; nested exception is: java.net.ConnectException: Connection timed out: connect

I also tried setting up smartermail for that domain thinking it would deliver locally then I could forward it on. It does deliver to that smartermail account but it cannot forward it to an outside email account. e.g. my personal email account on google.

So at this point I am not sure if this is an issue caused by CF, smartermail, DNS, IIS settings, or what? Anyone have any ideas or trouble shooting ideas?

have you tried using the username and password attributes in the cfmail tag?
