NW 6 SP2

I have 2 issues. Don't know if they are related or not.

1. Using Mail Proxy and Guinevere 2.0 or 1.14. Cannot send any email
to
anyone@aol.com. Can send to other domains, no problem. All AOL mail
is
bounced back. Have combed through header info. Cannot see where the
issue
is. This started today and I applied SP2 last night. Don't know if I
am
making connections that aren't there, but I am STUCK.

2. Users attempt to login to check their AOL mail via aol.com. Main
site
loads, but once user submits user name and password always get a 504 Gateway Timeout. Have not observed or been reported with other web
mail
clients.

If I need to post elsewhere, pls let me know. Many thanks for any
assistance. I have been researching all day long...
