How do I "reserve space for more" milters. I have been STFW-ing but with no results My milter is quiet simple. It just does a bsearch on a in-memory array , to find if the recipient has blacklisted / whitelisted the sender and takes action accordingly The array now has approx 200k elements, which should be nothing for 4GBRam box Thanks Ram
