I am running Postfix on Fedora FC3. I have a pretty large alias table. If the alias table is small, it works fine. Meaning it builds the alias database, and delivers mail correctly based on the alias table. But when I supply a large number of aliases (>1000), it seems to build the alias database fine (no errors), and postfix seems to be running fine, but it just ignore the aliases. I'm not sure if this is a size limit, or a problem with one of my aliases? But its copied directly from a sendmail server, where it works. Anything I should look for? Any way to debug? Thx, BM
