Hello,

We had a problem with mail fetching which stopped now and then since v7.5. Our problem was with the default settings to stop mail fetching. In v7.5 there are mail fetching settings which by default are checked (why?). These are under:

Admin -> Settings -> Mail fetching settings.

Uncheck both options ("Suppress auto-notification" and "Stop email fetching") and everything works fine again. (Or alter these to your needs).
