  • Relay Access Denied

    I have a problem with this one PC. The other computers are not affected in the office.
    The user is using outlook 2003. she's using SMTP to connect to the Exchange server.
    She's using an ADSL modem to connect to the internet.

    Whenever she tries to send an e-mail, she gets an undeliverable mail report displaying this error "Relay access denied".

    I've been searching for solutions on the internet all day and this is what they suggested:

    1. Make sure that "My outgoing server (SMTP) requires authentification" is checked in your Outgoing server settings.
    tried it and it still gives me the same error.

    2. I also tried to change my outgoing server number from 25 to 587.
    The error doesn't appear anymore but now i get another error stating that it can't connect to my outgoing SMTP server

    Any help would be gladly appreciated.

    Thanking you in advance

    Exchange is blocking relay for that user for some reason. Check the relay conditions in the vSMTP server in Exchange.

    Typically, by default relay is allowed for authenticated users. Make sure authentication is occurring and that her IP isn't in the relay blacklist.

    Read this KB article to get help testing that the user is properly authenticating.

      Well this user obviously has a user account in the domain otherwise she couldn't have an Exchange mailbox, so why not configure Outlook to connect to the Exchange server natively using MAPI instead of manually using SMTP and POP3?

            Re: Relay Access Denied

            Maybe I wasn't clear, sorry. You should not use IMAP or POP3 (for retreiving email) and SMTP (for sending email) directly to your email server from your Outlook client. When you configure Outlook you should select the Exchange server option, this tells Outlook to connect to Exchange natively using MAPI (messaging application programming interface) and therefore no relaying is involved. If you do configure Outlook to use IMAP or POP for retreving and SMTP for sending emails then you will have to configure Exchange to allow relaying either for authenticated users or for specific ip addresses. The simplest way to get Outlook working in an Exchange environment is to use the Exchange option when setting up the Outlook profile.

              tried choosing exchange when setting user up, doesn't connect to the exchange server.maybe its because she's not in our head office. Eberyone @ Headoffice accesses the E-mails using the exchange option. the other branches use POP3 to send\receive e-mails. all branches are in perfect working order except this one user.

                It sounds like there is a firewall between the user and the server. Have you tried setting up the server and client to use RPC over HTTP?

                  Please keep in mind that i'm new in the server world. If were to take an educated guess, i would say the server is configured correctly as other users dont have a problem. Question: How do you set up a client to use RPC over HTTP?

                  Thanx for your patience.

                      The problem got sorted out.

                      The problem was that the PC's ip address was assigned by the DHCP server automatically and it was pointing to the wrong Gateway and DNS server. I manually configured the IP address and everything is working Super.

                      Thanks for your help and Patience guys/gals, its been really appreciated.
