Help required setting up an SMTP server

[DivideBYZero]

I have my domain, I have set up my MX record and I can recieve email. The part I am having trouble with is setting it up to send mail out.

- SW is Desknow V3.0.9
- OS is XP pro
- MX record is setup and mail is recieved
- DNS, HTTP, HTTPS, POP3, SMTP ports are open on my firewall to this server. Tested.

I can't seem to find a solid answer anywhere on the web and I usually can. Can anyone help me send out emails from this server?

How about you tell us how your attempting to send out email and then we can help off of that.

Can't say I've dealt with Desknow but a quick search on google showed what I needed to know which was that it has a built-in mail server functionality. If you can receive email then I can only presume that the mail server is running which means it shouldn't have any issues sending out email.

You should include more information about what errors you get or what symptoms you see when you try sending email.

Get on the server and Start > run > type 'cmd' no quotes > then type:
telnet localhost 25

See what shows up.

Your ISP might block it.

Yep, some ISPs block port 25 to prevent people infected with worms from being used to send out tons of spam.

Try setting your SMTP server port to something non-standard and try it.

I don't know how to set it up to send out, was that not clear?

I can get IN to port 25 from outside, that's not a problem, i.e., not blocked. If my SMTP port is not 25, what use is that? The MX record would not enable mail routing to my domain, right?

Providers typically block OUTGOING smtp to anyone other then themselves. When I was on Optimum Online I would need to use their smtp mail server as a mail relay for it to work.
Try this: Start->Run->telnet gmail-smtp-in.l.google.com 25
(That connects to gmail's mail server)
You should see something like "220 mx.gmail.com ESMTP" come up, if it just sits there blank then most likely you're blocked. Check your ISP and try using their mail server as a relay.

I've used QK SMTP server from time to time on my desktop. Don't know anything about Desknow.

Nope, that worked! So no blockage. What am I missing? 😕

It depends on what host you are sending it to. Some hosts block any mail from a server that does not have a reverse IP.

EDIT: Scratch that it appears that most home provider's IPs do...

Well what actually happens when you try to send the mail out?
Does it bounce back with an error? or does it just disappear and act like it was sent?
