With or without sendmail's "excessive" schemes of lookups? [ e.g. up to seven (?) loops for virtusertable, four lookups per IPv4 address even without CIDR support] With sendmail.cf changes number of lookups can be reduced "a few times+". > And since we don't have any compelling use-case for it, I let the > feature languish. It may be used to allow mimedefang (dynamically) control: * greeting pause * allowed rate of connections per given IP adress/net * allowed number of connections per given IP address/net IMHO I may make sense to create list of features with "secondary support" instead of deleting them (at once). *BUT* socket map based features will be "less portable" to other MTAs. _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.
