Review for Mailbox Alert by denali_uk
Rated 4 out of 5 stars
At first I was divided on this add-on. The customised sounds are great, but the pop-up window is fairly ugly compared with the built-in Thunderbird pop-up and there seems to be no way to have the default pop-up with the custom sounds.
However, the addition of the anonymously coded PopUp.exe utility mentioned on the Mailbox Alert website totally changes this. Pop-ups in the notification area are even better than the Thunderbird default.
Very nice work.
