AOL dns update?

[Stanley Horwitz]

Hello folks:

On http://www.qmail.org there's that update to fix problems dealing with
AOL's long DNS records. I apologize if this seems a stupid question, but
how to I apply this update to my Digital Unix qmail installation? There's
nothing in the update itself or in the faq file that covers this nor have
I located any relevant information in the archived postings for this list.

Thanks
