Hi all,
at work we use Roundcube acting as a mail client for the Dovecot
Imap server.
In Roundube the messages are parsed through the Imap BODYSTRUCTURE command
If a message contains forwarded messages and attachments and some of the
messages contains
a quote (") in the subject, then the resulting BODYSTRUCTURE appears to be
malformed.
---
After some digging through the code of Dovecot, it seems to me that the problem is related to the
function: imap_append_string_for_humans
defined at the line 120 of the file src/lib-imap/imap-quote.c (dovecot sources
v. 2.2.29)
Said function is supposed to return a quoted version of the input string while
removing unwanted
characters from the input data.
But, if I call it with a string containing quotes as argument (eg: I am a lazy
" programmer) in
the resulting output the quotes aren't escaped and the output string is not
quoted.
----
This is related to the stated issue through the function calls in:
part_write_body [ defined at line 142 of imap-bodystructure.c ]
which calls imap_envelope_write [defined at line 46 of imap-envelope.c]
which finally calls imap_append_string_for_humans

Thank you for your time.
Best regards,
Giovanni S. Fois
