[Plugin: MailPress] Email validation bug

There’s a bug when sending an email that prevents camel cased email addresses from being used. For example:

[email protected] doesn’t work even though it’s a perfectly valid email address.

Further, there has been no update from the developer on this though a fix has been submitted:

Use only if every email you can conceivably send to is lowercase.
