Hello Noel, As I checked with "http://www.postfix.org/announcements.html" I found the following current stable version of postfix mail server. But I do not find any RPM for the same.
# August 28, 2009: Stable release Postfix 2.6.5. Currently I am using postfix version as resulted with # postconf mail_version command. So can you please tell me is it ok to use this version on my production servers? [r...@ns ~]# postconf mail_version mail_version = 2.5.6 -- Manoj M.
