I need to know of my version of Postfix supports a feature, given rh version numbers don't really tell you much I was trying to find an errata on postfix or anything to let me know the real version of it. How does one deal with this scenario? Is there a source of info to determine this info? Thanks! jlc -------------- next part -------------- An HTML attachment was scrubbed...
