I am having trouble getting mail from an organization that used a smarthost for our group. I switched from exchange to web based and all other mail seems to be going through our hosts servers/dns but this org. keeps hitting the old exchange server. There IT said they removed the smarthost but problem still exists (btw- MY boss is on my a$$ because of this of course and they seems clueless to solve). Is it possible that their contacts (us) are cached?? will deleting all contacts pointing to us and re-entering them solve this??
Any ideas are greatly appreciated.
