IMP does not recognize ICS attachments on CentOS/RHEL 6

attached invitation email was generated using open-xchange.

Tue, 06 May 2014 21:23:19 +0000

attached invitation email was generated using open-xchange. gmail / OX will recognize it, however horde will not on our system - will display HTML contents instead. however, same email sent to a friend who is running horde on latest stable debian had no trouble viewing + accepting the invitation, so probably this is (besides the strange unicode mail encoding problem I reported earlier) another case of Horde vs RHEL 6 / php incompatibility? Is there anything that could be done to improve this (other than waiting for CentOS 7? ;) thanks, guenter

This seems to indicate that you simply don't have IMP config

This seems to indicate that you simply don't have IMP configured to handle itip data on your CentOS system. It is instead displaying the previous alternative (the HTML part). The Debian screenshot is of a system setup to handle itip (i.e. text/calendar) data. text/calendar data has nothing to do with HTML (libxml2) parsing, so this is not the same issue as #13122.

I can verify that the sample message attached displays the itip data on my installation.

Same thing here. ics files are not shown when received in an e-mail. But if I reply to the e-mail, now the ics is displayed correctly. Attached you will find 2 images showing this. Everything else works fineas far as tested, in horde, IMP and kronolith. On the same Centos i have a working installation of (horde) 3.3.10, IMP H3 (4.3.10) and (kronolith) H3 (2.3.4) . There are no problems with ICS files in that installation. Horde 6 installation was made via PEAR. There are no errors in log /etc/redhat-release CentOS release 6.5 (Final)

Someone who is experiencing this has to track down the underlying cause. As mentioned previously, I installed CentOS 6.5 and could not reproduce on a default setup so there's nothing more us developers can do to track this down.
