yeah, sadly over time the email aliases are becoming less and less
useful.

Note that the SPF record for fedoraproject is: 

fedoraproject.org descriptive text "v=spf1 a a:mailers.fedoraproject.org 
ip4:38.145.60.11 ip4:38.145.60.12 ?all"

which has ?all at the end, which is _supposed_ to mean
"Interpreted as None / No policy"
So, providers should not care about this, but of course some providers
probibly ignore all that and treat any spf record as deny all.

To my knowledge, CentOS never provided aliases for maintainers.
Things from @centos.org should normally be coming from official/expected
IP's and allowed. I could of course be wrong...
