Hi
I suspect the IP address has been blocked and most likely to many failed logins is usually the cause but not always and could be dynamic IP from BT where last user sent spam etc...
I think AOL will auto release block after 24 hours but if above is correct, and continued failed logins keep happening, then the temp block would most likely turn to perm block.
We have this on all our platforms but temp ban is shorter then 24 Hours on our platforms.
I could be wrong sorry
Also, sorry I could not see URL in screen-scrape but and clicking mail icon from aol does not show that URL, so guess it might be connected with missing sessions and/or cookies etc...
Many thanks
John
