[stunnel-users] Stunnel Testing

[Robert Lambrecht]

I am using a command line mailer (BLAT) from a batch file to notify me when
errors occur.  My ISP requires SSL however still allows non-SSL traffic on
Port 25 as well.

 

Here is my scenario:

I use BLAT to send an SMTP message on Port 25 to my ISP.  This works but I
must send my userid and password which I don't want to do.

 

I then use Stunnel with the following config:

 

[smtps]

accept = 25

connect = smtp.isp.domain.net:465

 

Port 465 is the SSL port for my ISP.

 

I run Stunnel as a service in Vista.

I then have BLAT send an SMTP message on Port 25 to my ISP.  This works.

 

My question is, everything seems to work but how can I test this?

 

I'm trying to figure out if it really worked (I sent the message with SSL to
port 465) or I am still just sending a message on Port 25.  Since both of
these cases work, it is hard for me to tell.

 

I've tried to telnet to these ports; however, since I basically have to
specify port 25 in either case for the test, I'm not sure that I am
successful.

 

Any thoughts on how to make sure my messages are going through SSL?
