maps-scan - Checks listing status on mail-abuse.org's RBLs
maps-scan [-h] [-d delay] [-v] [-m regexp] [-M regexp] IPs
This script automates the task of verifying that your address space is in one of the mail-abuse.org's RBL. You can supply a single host, a subnet or a list of hosts or subnets in the command line. Every host is listed against said RBLs.
Queries are done through HTTP, as these lists are in the process of becoming private.
In general, it is not polite to send large numbers of queries to a host, as this might be interpreted as an attack. Use this scipt judiciously and avoid long and repeated queries.
Note that mail-abuse.org has a limit on the number of queries allowed per hour. If you need to scan an address block using this tool, you should probably use a delay of a few minutes between queries, using the -d option.
The following options are recognized:
Outputs this documentation.
- -d delay
Delay in seconds between a set of queries to the RBLs. Defaults to 60 seconds, which is ok for ocassional scans of a few addresses. If you need to scan larger blocks, increase the delay so that the abuse prevention mechanisms don not block you.
- -m regexp
Only query RBLs whose tags match the given regular expression.
- -M regexp
Similar to -m, but the regexp must not match to use the given RBL.
This is very useful as there are some RBLs that match a significant proportion of the address space or that are not helpful in your particular scenario.
Another potential use of -M and -m, is to taylor the list of RBLs to search in order to speed up the lookups. This is specially true if you are interested in a scan of a large piece of address space.
Be verbose about progress.
