Hi Kevin,
Just to get you started can we confirm connectivity to the server:
# host smtp.verizon.net
# ping smtp.verizon.net
Then see if you can open a session using telnet on all the ports and run
the SMTP hello message:
# telnet smtp.verizon.net 25
ehlo hostname
# telnet smtp.verizon.net 465
ehlo hostname
# telnet smtp.verizon.net 587
ehlo hostname
With these we should be able to judge connectivity and available options
on the ports.
Thanks,
Michael
