The sender address starts
"mailto:...
That's a malformed sender address. Because they're authenticated, Exim is assuming the malformed address is in the local server's primary domain and making it fully qualified, which then subsequently gets rejected.
The 'Restricted characters' bit is secondary, that error being generated by the resulting bounce message.
Sort your client out so it's using a valid sender address.
