Are they remote users where they VPN or dial in to your LAN ? Have you enabled POP3 support on your IMC and if so, have you configured the IP addresses allowed to relay ? Did you restart the IMC ?
Ask yourself these questions and see how you get on. ...knighTslayer... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Mike Strock Sent: 02 February 2003 07:24 To: Exchange Discussions Subject: 550 errors I'm administering a 5.5 box, SP3 installed. I've got a couple users who have switched to using POP3/SMTP through this machine (they are remote users now). They are getting a message when trying to send mail to users outside the default domain of '550, relaying prohibited'. I've had them set it such that they have checked 'Server requires authentication' and had them put in their username/password for the domain. One user is using Outlook Express, one is using Outlook 2000. How can I correct this? Thanks.
