Update to my CF9 Mail spool issue
I wanted to post an update to my post a few days ago about slow mail sending performance from my ColdFusion 9 server. To summarize my previous post, I was seeing much slower performance from my Cold Fusion 9 server when sending ".mail" files from the mail spool to my smto server. In the past, I had ColdFusion7 installed on the same box with Exchange 2003 and sent my bulk emails directly to the local mailserver. When I moved to a new server recently with ColdFusion 9, I started to send the mail to the old exchange server on the same network. The amount of time it took to send all of the messages from the spool to the email server dramatically increased. I switched my setup to include a local smtp server on the same box and used that smtp server to relay the mail to the exchange server and the speed dramatically increased and it now seem to be as fast as my old setup with the local smtp server.
So, this makes me wonder what the general practice is with sending large amounts of email from a ColdFusion server. Do most people use a local smtp server, a smtp server on the same LAN, or externally hosted smtp servers? In my experience so far, the amount of time to send the emails is dramaticlly different and I'm wondering if others are seeing this as well?
