Mandatory? I'm googling, but can't find a document that declares it mandatory and only sendmail seems to do it. I think it is lame to use DNS info to rewrite e-mail addresses, but the person who made it 'mandatory' will have good reasons for it.

Does somebody have a pointer to the specs about this?

offtopic, but why do some mailers replace a CNAME in a mail-address?

Because it used to be manditory to do so.  If you don't want it to
be done use a MX record.

        klop.yi.org MX 0 thuis.klop.ws

If you need klop.yi.org to have a address record then give it one.

        klop.yi.org A 212.123.145.58

r...@sheeva2:/var/vmail# host klop.yi.org
klop.yi.org             CNAME   thuis.klop.ws
thuis.klop.ws           A       212.123.145.58

It is not the first time that I'm bitten by this, but I never understood =

it.
