Detect attachments with Content-Type: ...; name=

Reviewed-With: Jared Hancock <jared@osticket.com>

RFC2045, section 5.1 seems to indicate that arbitrary parameters can be
appended to a Content-Type header specification. Some email clients seem to
use the Content-Type header to specify an attachment without giving a
separate Content-Disposition header normally used to signify attachments.

This patch corrects attachment detection for piped emails to detect such
emails. The patch also correctly decodes filenames specified either in the
Content-Disposition or Content-Type headers using RFC5987, where the
filename can be encoded using an arbitrary character set (ie, not us-ascii).

Fix 1.6-* upgrade to 1.7.1

Reviewed-By: Peter Rotich <peter@osticket.com>

8e72e521 (v1.7.1.2+) introduced a bug where
osTicket version 1.6 would not send a cookie (by calling PHP
session_start()) for the login page. Therefore, after unpacking the 1.7.1
source code, an upgrade would not be possible, because a login would never
be processed correctly.

Fix email address comparison issue

When comparing the From address of incoming email. If the ticket owner sent
an email back into the system and the email address did not match exactly,
case-wise, the email would not be considered from the ticket owner.

This is safe now, because the title is appropriately encoded in

if the domain given in HTTP_HOST variable happens to have a port
specification. Technically, the port specification should not be included in
the domain spec given in the cookie.

(And for the record, that makes no sense to me, seeing as a cookie would
otherwise be valid for all servers on any ports at a particular domain).

The previous implementation did not work correctly for symlinked folders.
The new approach uses debug_backtrace() and ROOT_DIR to determine the
difference between ROOT_DIR and the osTicket installation path.

Also, allow for the administrator to manually define the ROOT_PATH in the

If an alert message manages to loop back into the ticketing system, refuse
posting to the ticket thread. Technically, the message should be marked as
an auto-response message; however, auto-response messages should usually be
allowed to be appended to the ticket thread.

This patch will check if the From email header cites an email address that
is a system email address (visible in the Emails section of the Admin
Panel). If it is, the email is completely ignored.
