Thanks, Tripp, for the verification on domain name variants of form 'xxx.domain.com' in the 'url-domain-bl.txt' file.
I am inferring from your reply on whether or not the 'url-domain-bl.txt' file needs to be sorted that IMail performs an exhaustive linear search (ie. the entire 'url-domain-bl.txt' file is searched for exclusion of a domain name). That means that as entries are added to the 'url-domain-bl.txt' file, it will progressively take longer and longer to search the file. Therefore, would it not be more efficient to remove domain name variants in the file and replace them with a single domain name entry? The reason I am asking is that I performed a right-to-left sort of the Ipswitch 'url-domain-bl.txt' distribution file which revealed a high number of domain name variants. I would like to know the reason (technical, political, liability, etc.) why Ipswitch does not replace the many domain name variants in this file with a single domain name. If Ipswitch chooses not to do this with file distributions, I would still like to do this for our own 'url-domain-bl.txt' file and was wondering what the possible drawbacks are. All the best!
