FILEMAXL defaults to 100000, and MAILMAXL defaults to FILEMAXL. This reflects a correction to the master 1.8d documentation that I don't think has made it into the 1.8d beta docs online yet. FWIW you should raise FILEMAXL in preference to raising MAILMAXL. MAILMAXL was added years ago to solve a very specific problem on VM BITNET servers. Our recommendation is therefore to raise FILEMAXL if need be, but frankly unless you're dealing with multiple-megabyte messages, you probably don't need to raise this value. 100K lines of only 50 characters each is still 5MB...
