I have set up my new exchange 2010 server to send mail via Google smtp - How to use Gmail as your SMTP server
The issue with this is I will be sending mail from more than 1 account and google replaces the from and reply to on every mail, does anyone know of an SMTP redirect thats free for low usage users (20 emails a day at most) and would probably have 5 users max.
I did post this at the end of another post but I feel it needs its own thread ;)
Try talking to your ISP or simply sending it directly, you don't need to send it via another host and that an actually add delays. It is only if your IP is blacklisted by some retarded blacklist or your ISP is being dochie about ports.
Virgin do the same, they mark your outgoing with your virgin media email address. If I send direct I get refused as spam as I send via a dnydns and my home ip is masked.
I know it's not free, but I'd suggest DYN standard smtp, costs $20 a year and with a dynamic IP address does the job :)
