Hello All,

One question before you retire for your weekends.

Does anyone know if these days Yahoo sends out their e-mails via
an intermediate server called sun.mmic.net ??

I do some checks for Yahoo servers to keep spammers at bay. If the
mail is not delivered DIRECTLy by Yahoo servers to my server then I
politely reject it. A new development has caught me unawares though:

I have some funny scenario here:

A user johdoe@??? sends an e-mail to mabibi@???. This
mail is forwarded to validclient@???

When this mail hits wananchi.com, it's arriving via sun.mmic.net. Now
I am wondering if this is a valid Yahoo server??? Shall I trust it?

Below is one e-mail that johdoe@yahoo receives once I have rejected
their mail (because it's not from a Yahoo server). :-))

Hi. This is the qmail-send program at sun.mmic.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<validclient@???>:
62.8.64.4 failed after I sent the message.
Remote host said: 550 No thank you: please send through Yahoo servers

--- Below this line is a copy of the message.
