I have a question, are all values in the function mandatory?

in autoit any parameters within brackets are NOT mandatory.

ie:

Code:

_CompSMTPmail($Username, $Password, $From, $To, $Subject, $Body, $smtp, $port[, $attachments = Chr(0])

You see that the [, $attachments = Chr(0] parameter is within the brackets. You can use the function without this, but the rest ARE mandatory.
