=over 4

Many people detest file-style folders because they store messages all in
one file, where a line starting with C<From > leads the header.  If we
receive a message from a file-based folder, we store that line.  If we write
to such a file, but there is no such line stored, then we try to generate
one.

If LINE is provided, then the starting line is set to this value.

I<Error:> Cannot include forward source as $include.

Unknown alternative for the L<forward(include)|Mail::Message::Construct::Forward/"Constructing a message">.  Valid choices are
C<NO>, C<INLINE>, C<ATTACH>, and C<ENCAPSULATE>.

I<Error:> Cannot include reply source as $include.

Unknown alternative for the C<include> option of L<reply()|Mail::Message::Construct::Reply/"Constructing a message">.  Valid
choices are C<NO>, C<INLINE>, and C<ATTACH>.

I<Error:> No address to create forwarded to.

If a forward message is created, a destination address must be specified.

I<Error:> No default mailer found to send message.

The message L<send()|Mail::Message/"The Message"> mechanism had not enough information to automatically
find a mail transfer agent to sent this message.  Specify a mailer
explicitly using the C<via> options.

I<Error:> Package $package does not implement $method.

Fatal error: the specific package (or one of its superclasses) does not
implement this method where it should. This message means that some other
related classes do implement this method however the class at hand does
not.  Probably you should investigate this and probably inform the author
of the package.

I<Error:> Unable to read delayed body.


I<Error:> forwardAttach requires a preamble object


I<Error:> forwardEncapsulate requires a preamble object


I<Error:> no rebuild rule $name defined.
