Yahoogroups

Mail to yahoogroups for two days is giving some strange responses.

Mail is attempting to go to 172.16.3.10 when sent to a yahoogroup.

This looks real strange....that block is reserved I believe? Wondering why theyre resolving to that address?

Router mismanagement? Poisoning?

I dont know...but its causing some grief here...
Yahoo is real lax in giving some human contact addy, perhaps the esteemed group here can shed some light...

Thanks..

$ host -t mx groups.yahoo.com
groups.yahoo.com is an alias for groups1.vip.scd.yahoo.com.
groups1.vip.scd.yahoo.com mail is handled by 1 mta2.grp.scd.yahoo.com.
groups1.vip.scd.yahoo.com mail is handled by 1 mta3.grp.scd.yahoo.com.
groups1.vip.scd.yahoo.com mail is handled by 1 mta1.grp.scd.yahoo.com.

ok, so:

$ host mta2.grp.scd.yahoo.com
mta2.grp.scd.yahoo.com has address 66.218.66.217
$ host mta3.grp.scd.yahoo.com
mta3.grp.scd.yahoo.com has address 66.218.66.218
$ host mta1.grp.scd.yahoo.com
mta1.grp.scd.yahoo.com has address 66.218.66.216

Where's the RFC1918 in that?

Maybe the problem is fixed already.

Yahoo! does use RFC 1918 space internally, but we're not using that block.
Therefore it's (hopefully) not something gone wacky on our end. Do you
have access to a command line somewhere that you can run dig from? If so,
please mail me privately and we can try to work out what's going on.
