Using SME 6.01-01 with swerts-knudsen Clamd and rbl blacklists.  Since yesterday, I have 3 servers not sending out email from the local lan...one of the three does not have clamAV installed, but has same problem.  

Setting the timeout period to 5 minutes for smtp in Outlook is allowing the messages to get sent, sometimes.  

Anyone know any issues with the popular rbl dns blacklist sites?  I don't think I can have 3 servers in 3 different locations with the identical problem.  

Only other issue is critical updates for XP have been applied as of this morning on clients involved with this problem.

Thanks for any input.

SOLVED....the dns rbl at blackholes.us is offline.  I was using multiple lookups at blackholes.us causing frontmail to appear to be non responsive to LAN requests.
