sending mail

Recommended Posts

To prevent spam mail, mail sent by software who fake the From: address, almost all mail servers refuse mail sent from an IP number that is not in their local network, unless the sender is a trusted mail server (listed as smtp server for that domain).

What you should do is connect to your provider''s mail server. This is the one set as the SMTP server in your outlook.

So if you use provider.com, you send mail to smtp.provider.com, this mailserver sends it to smtp.hotmail.com and this server delivers it into a mailbox.

Wrong. If mail servers refuse mail sent from an IP number that is not in their local network, no mail would ever come in from outside the network! As long as the recipient of the message is in the domain that the SMTP server is accepting for, it should be fine.

As proof, I created a hotmail address. Then on my laptop, went to a command prompt and:

C:\>telnet mx1.hotmail.com 25

Connection to host lost.

In my hotmail account inbox, there was a message from "someuser@somedomain.com".

One problem that the OP might be having is that the host hotmail.com does not accept e-mail. If you do an MX record lookup you'll see that hotmail.com's mail servers are:
mx1.hotmail.com internet address = 65.54.252.99
mx1.hotmail.com internet address = 65.54.166.99
mx1.hotmail.com internet address = 64.4.50.99
mx1.hotmail.com internet address = 65.54.254.129
mx2.hotmail.com internet address = 65.54.166.230
mx2.hotmail.com internet address = 65.54.254.145
mx2.hotmail.com internet address = 65.54.252.230
mx3.hotmail.com internet address = 65.54.167.5
mx3.hotmail.com internet address = 64.4.50.239
mx3.hotmail.com internet address = 65.54.254.140
mx3.hotmail.com internet address = 65.54.253.99
mx4.hotmail.com internet address = 65.54.167.230
mx4.hotmail.com internet address = 65.54.254.151
mx4.hotmail.com internet address = 65.54.253.230
ns1.hotmail.com internet address = 216.200.206.140
ns3.hotmail.com internet address = 209.185.130.68
ns2.hotmail.com internet address = 216.200.206.139
ns4.hotmail.com internet address = 64.4.29.24

You should be able to establish a connection to those addresses on TCP port 25, and send all the mail you want to a hotmail.com address.
