not really. The best you can do is : not to relay messages for domains
to gmail and others.

This will reduce problems with gmail & co  to a minimum.

But, customers are liking gmails webmail, for what i don't have any
explanation,
as it's worse than roundcube. (RC is fine \o/ )

SPF makes entirely sense, is easy to setup and easy to maintain if your
not google yourself.
There is no good reason to not use it nor to make an entry for your domain.

"Postmaster@" if you want spam all day long, which you have to read, to
filter out that one
important message a year/or in life that gets send to it ..  it's your
wasted lifetime. 

I can understand anyone, not to receive messages via abuse@ or
webmaster@ or postmaster@,
as letting it bounce with a 550 and let that one-in-a-lifetime-user use
you contact-email from your webpage,
seems to be a fair way to deal with that "should" (even if it would be a
"must").
