I have inherited a set of Ubuntu boxes (different versions) that process emails and replies using postfix and other tools.
Two Ubuntu 14.10 boxes have started giving out incorrect results and after investigating a little closer I noticed that the version of postfix has changed on those two machines and I am not able to revert back to the old version.
The version that should be installed is 2.11.0 but these were updated to 2.11.1.
I am not able to find the previous version in the apt repositories. Is there any way I can install 2.11.0 using apt or do I need to look for the source and install from scratch?
