#1) When viewing the Security->Whitelist as the admin, you can't see the full IP address range (from-to).  The solution is simple -- space out the columns better and give less room to POP, IMAP, etc. which only need enough space for a Yes or No.

 

#2) Add a new column to bypass spam filtering. Then you can remove this obscure check box in the Antispam Options tab:

 

This would give the admin more granular control of spam filtering and make SM more intuitive because the above check box is hidden.

 

Thanks,
