Block access ( HTTP / SMTP ) for entire countries instead of separated ipranges

We need to block certain countries from accessing Domino by HTTP and/or SMTP. For now SMTP is important. Now it's not possible because the amount of ipranges per/country are huge. Like Russia: 45,315,584 ipaddresses and 8799 ip-ranges. If you add those into the Domino to block them ( Deny connections from the following SMTP internet hostnames/IP addresses: ) this fieldlimit ( 32K ) will not allow to add them all.

The same with blocking by adding into groups. Domino will tell you that the GroupExpansion failed because it's too large.


We need a way that we can import those ipranges into a database and that Domino SMTP checks those ranges.

      Usually this type of enforcement should be done on network level, not on SMTP level.
      IMHO this isn't something implemented for one protocol only and this isn't only relevant for SMTP.

      this isn't about "good idea" only. But about how this is rated in relation to other ideas and how many customers need it.

      In Exchange we can do the trick, we can block entire country's. The iprange-tables / region's are updated every week. Works perfectly. Even a community/free SMTP service "MailScanner" can block by Country.

      It was in my opinion that the amount of votes does not matter. :-) It's a good idea or it's not.
