sendmail m4 issue
2011-01-20 by Joe Pruett
i recently upgraded to 4.2.6 with no troubles. i then installed it fresh on a new system and sendmail wouldn't start. i tracked it down to a trailing comma in the sendmail.cf left there by the milter-greylist.m4 config file. the update didn't get triggered because the sendmail cf logic isn't smart enough to rebuild if a feature file changes. i'm working on a tweak to the m4 to deal with this, but wanted to give a heads up to folks.
