Comments received via incoming mail aren't triggering notifications

The incoming mail module is no longer functioning correctly for us. This is a rather critical issue. The symptoms are:

- Anything you do via the web that triggers an email notification (eg, post a comment to a ticket that has subscribers) will successfully dispatch that email notification and all valid recipients will receive it. This is working fine.

- However, if you reply to a notification from your email client, that message will be successfully delivered to the incoming mail account's mailbox and activeCollab's script in cron will successfully pick it up, parse it, and place the comment in the right ticket or discussion. But, unlike if you had posted this via the web, the system isn't dispatching an email to the other subscribers to the ticket/discussion. Until recently, this was working correctly.

I poked around, and it looks like the incoming mails that it fails on are sitting in the table `acx_incoming_mails`.

Dusan,

I replied to your support request response. Clearly you either did not understand the problem as described or you did not fully investigate the matter. The problem persists and can be readily and easily duplicated on any ticket or discussion. This issue has nothing to do with spam filters, as I can verify that activeCollab is never attempting to send the emails in the first place.

Ilija,

As I recommended to Dusan when I explained the memory exhaustion issue, I recommend you add a sanity check to the activeCollab installation script that ensures the memory_limit of the CLI PHP is sufficiently high.
