Hello, was wondering if someone could offer a suggestion. I'm running FC2, with sendmail-8.12.11-4.6. I'm wanting to set up spam filtering (and possibly virus filtering) on my working sendmail mail server. From the posts I've read on this list, it looks like MIMEDefang is a good way to go about intergrating sendmail with spamassassin. I've been following the HOWTO linked off of the main MIMEDefang page and ran into this: In versions prior to 8.13.0, sendmail did not support mail filters by default, and must be compiled with filter support enabled by defining -DMILTER. To do this, create devtools/Site/site.config.m4 with the following lines: dnl Milter APPENDDEF(`conf_sendmail_ENVDEF', `-DMILTER') APPENDDEF(`conf_libmilter_ENVDEF', `-D_FFR_MILTER_ROOT_UNSAFE') ---- As I do not wish to blow up my mail server, I'm asking what would be the best plan of attack? Upgrade to the latest Sendmail, if yes, how? From tarball? I did not see any updated sendmail RPM's for FC2. Or should I install the sendmail-8.12.11-4.6 source and rebuild it with the above lines? Or maybe I should be looking at an easier way to combat spam? If so, what? I'm a sendmail newbie, so whoever responds to this message please don't spare any details! TIA, Julian
