Problem with ‘Send Mail’ in VBP 5.6

[itai]

Hi

I have a ‘Send Mail’ step in my VBP project.
When used on previous versions (5.5, 5.4a) it worked just fine giving me a “Message successfully sent” log.

After upgrading to 5.6 the same ‘Send Mail’ step returns the following error:
///////////////////////////////////////////////
Connecting to SMTP server '10.1.20.11' on port 25
Error authenticating user: The specified option is not supported on this server (xmail.Comany.com Hello [10.1.20.132] )
Step 'email file sizes' failed
Build ended.
///////////////////////////////////////////////

The step itself is very basic, on the Server tab I only set the ‘Mail Server’, ‘Username’, ‘Password’ and ‘Domain’ fields everything else is left with its default values.
