I am trying to connect to SMTPS using Net::SMTP::SSL; library. while tryin to connect I am getting an error which says.. IO::Socket::INET configuration failederror:00000000:lib(0):func(0):reason(0) I am able to connect to SMTP. I have tried the same with telnet and telnets which was successfull. Can anyone please give me some ideas about this error? Thanks in Advance Ravi Gowda

Are you sure you talk to an SMTP server which talks SSL directly?
There are two ways to do SSL within SMTP, one is to just tunnel SMTP within an SSL connection (this is what Net::SMTP::SSL supports) and the other is to have a normal SMTP server (usually sitting at port 25), start a unencrypted session and then switch with STARTTLS command to an SSL session. This is unsupported by Net::SMTP::SSL.
If you are sure that you try to use Net::SMTP::SSL in the intended way (tunnel SMTP through SSL instead STARTTLS on plain connection) you could post an example program which shows your problem (please with the real server) so I could have a look at it.

Also some additional information: I get the same exact error when I have the initial call as:

or

And I have another perl program on the same machine (In the same directory even) that uses IO::Socket::SSL to make https requests (Via LWP::UserAgent), which works perfectly. I'm not actually sure this is an issue directly related to IO::Socket::SSL and not Net::SMTP or Net::SMTP::SSL (Although the latter simply substitutes IO::Socket::SSL for IO::Socket::INET in the former)
