RC 1.2 - Corrupted e-mail headers while sending an html empty message

sgironella · July 14, 2016, 04:49:14 AM

Hi, I've noticed a strange behavior while sending an empty content e-mail when the html editor is enabled.

I'm using a fresh RC 1.2 install without additional plugins / custom config / etc.

In this example I'm using the same account for sending / receiving, but the issue occour even on different accounts.

This is the source of the sent e-mail (taken from 'sent' mailbox):

Code Select

</body></html>

While that's what i receive (taken from 'inbox' mailbox):

As you can see, sending an html e-mail will lead to use a 'multipart' content-type to have both html and plain text contents, but the received e-mail has a different content-type (text/html) so it will be shown in this way (parts are treated as simple text):

Code Select


--=_b492bde5ebec2fd2cd9973a3683f42a9 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=US-ASCII --=_b492bde5ebec2fd2cd9973a3683f42a9 Content-Transfer-Encoding: quoted-printable Content-Type: text/html; charset=UTF-8
--=_b492bde5ebec2fd2cd9973a3683f42a9--

Any ideas?

I'm facing that problem too. Did you solve it?
