The error is:

 

An invalid character was found in the mail header: 'Ś'.

 

It looks like you have tried to specify some cuatom headers in the email mesage to be sent out, and one of those headers contaioned a character that the .NET email sending task considers to be invalid.

 

The solution is most likely to only use standard ASCII letters/numbers in the email headers.
