I have a user who has notes 6.0 on his computer in a remote location,he is not part of the domain but uses a custom/interenet connection document. My server crashed monday and I reinstalled Domino 6.5 on same server and transferred all the DB’s,ID’s, etc. He can recieve mail,access his files but he gets this error when sending mail to anyone- Error 553, the domain isn’t in my list of allowed RCPThosts (#7.5.1). My inbound relay controlls have Deny messages to be sent to external internet set to *, with exceptions for a handfull of IP’s that are on the network. Anti-Relay checks are for External Hosts with the exception of authenticated users. Isn’t he considered an authenticated user?? Nothing has changed in my configuration that I am aware of. Any suggestions would be much appreciated.
