Hi I have set up my Email and now I can receive emails but
I can not send!
What could be wrong?
In netscape (to manage my email) I have set my domain name
neuads.com as incoming mail server
neuads.com as SMTP (Outgoing)
admin as outgoing username

It's probably one of two things. Either sendmail is denying relaying for you or your ISP is blocking you from connecting to SMTP servers other than their own.

Sendmail by default blocks relaying so you either have to enable relaying for everyone (not recommended..don't do it, if you do you'll be getting spam complaints until the cows come home), enable relaying for a specific domain or IP or range of IP's or install a pop-before-smtp program. Using pop-before-smtp is by far the way to go. I believe that Cobalt has a pop-before-smtp package designed for the RaQ but if they don't then there are some 3rd party packages that will do it too. I use poprelayd which is relatively easy to install and is relatively small. You can find it at http://poprelay.sourceforge.net/.

If you find that relaying is not the problem then most likely your ISP is blocking you from connecting to SMTP servers outside of their own. If this is the case then you are SOL. You'll either have to use their SMTP for outgoing mail or change your ISP.

I just added my own IP address to the list and it allows me to send email.
