Hello all,
I've recently posted a bug reporting to the Roundcube community forum
We have noticed a strange behavior with a fresh Roundcube 1.2 install (no additional plugins enabled nor 'strange' custom config defined).
To reproduce this, send an e-mail using the html editor, leaving a blank content.
Received e-mail has a 'text/html' content-type (instead of the expected 'multipart'). therefore client view raw mime-parts as e-mail content.
Note that sent e-mail (taken from sender 'sent' mailbox) has the right content-type (multipart) so it's perfectly readable.
In addition, we have recorded a tcpdump session, that confirm our impression of having two separate libraries handling in a different way SMPT (for delivery) and IMAP (for storing e-mail within 'sent' inbox) sections; that's what we got:
IMAP SESSION (save e-mail to 'sent' mailbox) - Note the right mime-type and boundary here
