Goodness. A while ago when times were good I got into the world of RedHat with version 6 and installed it onto a Compaq server. The server had Sendmail 8.9.3, Qpopper 3.0 and Apache 1.3.6 as it's main role in life. After numerous security breaches I decided to upgrade to Red Hat Linux 7.2 (enigma) and I have had one head ache after another.
My first question, although probably a no, is it possible to go back to Red Hat 6 and save all of the users and their e-mails?
If not, is their a place I can get some information on upgrading to sendmail 8.12.3 from my version?
The server is currently "running" Red Hat 7.2, Sendmail 8.9.3, Qpopper 4.0 and Apache (httpd 2.0.35). Thanks for your help!
