Regardless of the From address set on an individual copier, it still fails with a similar message.
On other copiers, I get a message that states connection refused. Same creds.
Setting the associated email address to the account on the copier does not work either.
I'm thinking that Xerox cannot parse domain credentials.
Searching outside thie forums I see this is a pretty common issue.
Any one have success sending email to an authenticated (not anonymous) Exchange connector? If so, advise what settings on the Exchange server need to be there, and what settings on the copiers send sucessfully.
Again, looking for a way not to add 100+ ip addresses to the Exchange connector and set the copiers with static addresses.
