hi i wonder what people's experiences are with using specialized smtp services. i already use smtp server http://www.smtp.com/corporate.html and it works great, but i need others like that and have had trouble finding them without buying into a whole package of other stuff that's not needed. and in case you are wondering, no, it's not for sending spam! i need to recommend smtp servers from time to time to corporate clients, and often they have specialized requirements. thank you for any insight!

and by the way, great forum! i look forward to using it more.

if your clients have specialised requirements then for the prices I see on the link you posted you could get a dedicated server and setup exim (or even microsoft exchange on windows 2003 server if you wanted) for less. Then you could then set it up however you wanted.
