Mantis Bug Tracker - Forums

Are there any plugins that let us set a date on a ticket and be reminded via email on that date?

There is an existing Remind Me plugin, but it requires manual use and is more like a *poke* feature imo. If we forget to remind them, well.. haha.

Maybe I'm searching for the wrong name, but is there something like a recall date we could use in Mantis?

The reminder plugin does not necessarily require manual intervention.
You can set up a cron (Linux) or Task (Windows) job to automate the sending of reminders. This is described in the readme.

That's a different functionality and would require console access to set up

How tricky would it be to build in a custom date to send a reminder on (for each individual ticket not as a whole)

Yuo could create a seperate plugin which adds a date field to each issue. You still would need to set up a scheduled job to automate the sending of a message (in which ever format).
