I find that using SG has reduced SPAM to negligible quantities.
Thus, it means that on any new SG address created, I have to go and change it to unlimited (by entering "." in the 'Exclusive Sender' field).
Having to do this for each new SG address becomes irritating after a few hundred addresses.
What say you to changing the default of SG addresses to being without limit?
(Of course, if one finds that a certain address starts being used by spammers, only then one'd login to SG, and set that address' 'Max Count' to 0,
but - as I said, this becomes a very rare instance after one starts using SG)
