A question about Acl

If I was asked to only permit the internet to access my smtp server with ip
10.10.1.1,which acl is better?

access-list 101 permit tcp any 128.88.0.0 0.0.255.255 established
access-list 101 permit tcp any host 128.88.1.2 eq 25

or

access-list 102 permit tcp any host 128.88.1.2 eq 25

I am a bit confused with it.In my option,since the mail packets coming in
from the internet have a destination port of 25,I think acl 102 is
enough,but many other people prefer acl 101.

Any clarify is appreciated.
