I have one user who cannot send e-mail outside. He can send internal mail, receive internal and external mail but cannot send external mail. I have tried re-registering him with a brand new mail file, running a fixup, compact and updall on his mail file, checked all settings, created a new copy of his database, checking his ACL, checked all client configurations but still no luck. The wierd part is that he is the only one who cannot send out mail. I then thought it might be his PC so I tried sending mail from another system and still the same problem. I even thought that it might be some corrupted documents so I created a copy of his mail file and deleted the documents as a test. Still doesn't work! PLEASE HELP!! I'M OUT OF IDEAS.
