Hello

I tried the VBA example.
Filled in all fields.
I've tried to use IP address instead of mail server name.
I've tried to add domain to user name (domain\username).
I've tried all authentication types and everytime I get the same errors:

None (without Username and Password):

Connecting to SMTP server
Error 10053: Software caused connection abort.

Login (with Username and Password):

Connecting to SMTP server
Error 10053: Software caused connection abort.

Plain (with Username and Password):

Connecting to SMTP server
Error 10053: Software caused connection abort.

POP3 (with Username and Password en POP3 server name):
(In status text I replaced POP server address with X characters):

Authenticating to POP3 server
Connected to POP3 server
+OK Microsoft Exchange Server 2003 POP3 server version 6.5.7638.1 (XXXXXXXXXXXXXXXX) ready.
+OK
+OK User successfully logged on.
+OK 44 705195
Authenticated
+OK Microsoft Exchange Server 2003 POP3 server version 6.5.7638.1 signing off.
POP3 connection closed
Connecting to SMTP server
Error 10053: Software caused connection abort.

So what is wrong?

Thanks,

Most likely, the problem is caused by your firewall

SMTP Component requires port 25 to be opened for outgoing connections.
