Updated email processing.
- Added an option to enable smtp debugging via SMTP_DEBUG. This will trigger a trace of the smtp commands sent/received to/from the mail server. Useful when troubleshooting. - Added two options to ignore invalid certificates which either do not match at all, or only doesn't match the hostname. - Updated lettre to the latest alpha.4 version.
