Blocking entire netblocks

Postby Alyson_J » Tue Aug 13, 2002 4:45 am

Hi

I am currently having a problem where users of a Taiwan provider are constantly forging the from address and trying to dictionary attack my server and I would like to block the entire netblock.

I can enter the ip addresses in the SMTP access options but can I enter the whole range as follows?

61.216.0.0 - 61.219.255.255
211.72.0.0 - 211.127.255.255
168.95.0.0 - 168.255.255.255
210.242.0.0 - 210.242.127.255

Have you any ideas when the blocklist look ups and filtering will become available?

Thanks a lot
Aly

You can use wildcards for the IP ranges, but not a range how you indicate it (which is probably a bit awkward for the ranges you mentioned). For example:

61.216.0.0 - 61.219.255.255 would be:

61.216.*.*
61.217.*.*
61.218.*.*
61.219.*.*

RBL lookups are being tested and we should have a beta soon. Hopefully sometime in the next few days.

I am looking forward to RBL's as well...it is a much needed feature and I can't wait....this is the only thing that is holding me back from putting ME in full production at my company. I am a current ME Pro license holder and have been using it extensively for the last couple of months and really love everything about it. Especially the support from ME and this forum!!! :lol:
