I should point out that even if you only run sendmail for the benefit of machines on your own network, and even if you use a dialup (rather than always-on) connection, you want the ant-relay stuff. I see regular attempts to connect to port 25 on my hub, even though it's behind a dynamic IP address on an ISDN dialup (I also see regular attempts to connect to the telnet, ssh, and ftp ports, and others, maybe 2-3 times a week. If you run a common operating system, don't assume that a dynamic IP address, or NAT, or using a dialup, gives any worthwhile protection). > FWIW: rather than update sendmail and hack another .cf, I bought a > Windows-based mail server Nowadays, it's easy to use m4 to set up sendmail.cf for the common sorts of home use -- just define the settings for masquerading and smarthost, and press go (more or less). The only time you need to hack it a bit is if you want something unusual, like some mail going to the local machine and some forwarded to other machines on your network, or using UUCP. > Instead, I use my free time to hack 2.11BSD and UNIX v6! :-) I have to admit that sounds like a better use of the time :-) -- Pete Peter Turnbull Network Manager University of York
