Impossible to create message with empty plain text part

[alexandro]

I try to write a simple plugin, that allow to copy-past gpg-encrypted text and send it as PGP/Mime message.

PGP/Mime encrypted messages must not contain plain text part, but roundcube doesn't allow empty message body and "fix" body in program/steps/mail/sendmail.inc:

if (!strlen($message_body)) {
    // empty message body breaks attachment handling in drafts 
    $message_body = "\r\n";
}

I suppose we don't need this hack anymore. Need to investigate.

This is a fix for #1484506. We need to find another way.

I tested removal of this code and it works for me. However when body is empty then the message doesn't contain a text part at all. This is fine according to standard. Is this fine for your use-case too?

Yes, this is what i need, thank you!
rfc3156 require exactly two parts in email, no plain-text part allowed.
