The Software you are using is using
"mailto:myaddress@mydomain.com%22@??? (including
the opening, but no closing quote) as a sender address.

Exim rightfully refuses that.

To verify that it's actually your MUA software, you can try sending a
test message using swaks or manual SMTP on a telnet session:

MAIL FROM:<myaddess@???>
RCPT TO:<mntini@???>
DATA
.

And, please do not obfuscate. Having to figure out whether an obvious
error was added during obfuscation or whether one is looking at the
actual issue makes things so much harder for people trying to help.
