I've just run up a new KVM VM with CentOS 7, postfix, saslauthd (to  
LDAP on another VM), cyrus-imapd, amavisd-new, clamav, spamassassin,  
fail2ban - ready to migrate from an old CentOS 5 box running the same  
software.

I chose 7 as it is long EOL, I don't want to be doing the same thing  
again in 3 years! The old box ran sweet for 6 years.

I had no major dramas with it, there are some good improvements in the  
newer versions (e.g. postscreen in postfix), and I fixed up some  
config errors that had crept in over the years on the old box. I also  
used the opportunity to learn a lot more about some of the config  
settings that I just took for granted last time.

If you know CentOS then you will get the hang of 7 pretty quickly,  
even with the changes. Nothing that Google or mailing lists can't help  
you with.
