Connection timed out (Application error code 10160)..
You should verify your SMTP settings, and may want to check connectivity.
You can do that in a lot of ways. I'll show shell commands below.
First, let's check that your SMTP server resolves:
$ host your.smtp.server your.smtp.server has address a.b.c.d
Then, check the port you've configured in Mailsmith responds:
$ telnet your.smtp.server yourport Trying a.b.c.d... Connected to your.smtp.server. Escape character is '^]'.
If that all works while Mailsmith still cannot connect, I'd be surprised.
