Configuration help needed with Webconfig Mail Settings

[MichaelxW]

Hi there,

I am totally not sure if I am at the right place here...

My ISP recently changed their email servers and I use now Parallels Plesk Panel 11.09 for email admin.

The problem is my website where I can no longer fire emails from.
The ISP gave me all SSL and NON-SSL port numbers and I tried all in my Webconfig but to no avail.
The ISP says it can not help me with scripting issues but I all I want is the correct configuration in my Webconfig file.

Previously it all worked with only the host name, port number and default credentials = true.

Can anyone help please?

Many thanks in advance and have a great day...

Cheers
Michael
