I am running Imail Pro 8.05. I had a user mention that it was taking an a
long time for mail to be delivered to yahoo.com accounts.
I started checking the logs and it appears that my server is not picking the
"MX" record for yahoo.com, but instead the "A" record? I am probably
missing something, but here is the info I am seeing in the logs.

;; ANSWER SECTION:
114.71.218.66.in-addr.arpa. 1200 IN PTR w3.rc.scd.yahoo.com.
The ip addresses to select to send to are all "A" records of yahoo.com
C:\>nslookup yahoo.com
Server: X.ns.verio.net
Address: 129.250.35.250
Non-authoritative answer:
Name: yahoo.com
Addresses: 66.218.71.112, 66.218.71.113, 66.218.71.114, 216.109.127.28
216.109.127.29, 216.109.127.30
None of those addresses are listed as a MX for yahoo.com..
C:\>nslookup
