[Mailman-Users] Too many Bounce action notifications

[Vikram Goyal]

Funnily enough, the messages stopped the moment I sent the 
previous reply. As Mark suggested earlier, it could be because 
"all" the bounces happened at once because of the threshold 
coming at once.

Thanks everyone for their comments and suggestions.

Regards,
Vikram
