-
-Sends an error message. Takes a param hash:
-
-=over 4
-
-=item From - sender's address, by default is 'CorrespondAddress';
-
-=item To - recipient, by default is 'OwnerEmail';
-
-=item Bcc - optional Bcc recipients;
-
-=item Subject - subject of the message, default is 'There has been an error';
-
-=item Explanation - main content of the error, default value is 'Unexplained error';
-
-=item MIMEObj - optional MIME entity that's attached to the error mail, as well we
-add 'In-Reply-To' field to the error that points to this message.
-
-=item Attach - optional text that attached to the error as 'message/rfc822' part.
-
-=item LogLevel - log level under which we should write explanation message into the
-log, by default we log it as critical.

-=head2 SendEmail Entity => undef, [ Bounce => 0, Ticket => undef, Transaction => undef ]
-
-Sends an email (passed as a L<MIME::Entity> object C<ENTITY>) using
-RT's outgoing mail configuration. If C<BOUNCE> is passed, and is a
-true value, the message will be marked as an autogenerated error, if
-possible. Sets Date field of the head to now if it's not set.
-
-If the C<X-RT-Squelch> header is set to any true value, the mail will
-not be sent. One use is to let extensions easily cancel outgoing mail.
-
-Ticket and Transaction arguments are optional. If Transaction is
-specified and Ticket is not then ticket of the transaction is
-used, but only if the transaction belongs to a ticket.
-
-Returns 1 on success, 0 on error or -1 if message has no recipients
-and hasn't been sent.
-
-=head3 Signing and Encrypting
-
-This function as well signs and/or encrypts the message according to
-headers of a transaction's attachment or properties of a ticket's queue.
-To get full access to the configuration Ticket and/or Transaction
-arguments must be provided, but you can force behaviour using Sign
-and/or Encrypt arguments.
-
-The following precedence of arguments are used to figure out if
-the message should be encrypted and/or signed:
-
-* if Sign or Encrypt argument is defined then its value is used
-
-* else if Transaction's first attachment has X-RT-Sign or X-RT-Encrypt
-header field then it's value is used
-
-* else properties of a queue of the Ticket are used.
