I am on Ubuntu 12.04 using Thunderbird as email client. Both are up to date in terms of updates.

I have bunch of nightly jobs that do the work and send a status mail. It gets tedious if you keep getting same/similar mails every day so I ended up writing a mail filter rule which causes emails to end up in their respective folders automatically. If things are going ok, I really don't need to read emails. Failure emails are sent to different alias - if the job runs.

We recently discovered that one of the job had not run for few days as someone accidentally disabled it. In order to avoid such problems in future, I would like to setup thunderbird in such a way that if I don't get email from given address within given duration, it should alert me. My dream solution is to set up frequency - some jobs do run every 4 hours.

Is this possible? Can I setup Thunderbird (preferred) or other email client for reminding me when expected email does not show up.

Based on comments and answer I received, here are the reasons why I would like to use Thunderbird.

• We are already using Thunderbird. It has calender support via plugin, so I suppose someone is already watching time to remind us about the event. May be this another type of event.
• Additional job is one more failure point, may complicate life if it has to monitor multiple hosts.
• Additional tools - same thing, one more failure point.
• Thunderbird can be run across all the platforms we are using - Windows and Ubuntu. It sort of becomes platform independent solution.
