  • A relay issue?

    Didn't want to piggyback on a thread that's running a couple of posts below as the issue although similar is somewhat different.

    Thing is that one of the users works mostly from a location external to the office. He's got a couple of POP3 accounts configured in his Outlook and when he's at the office he can't send emails. Obviously he doesn't want any changes done to the configuration of his accounts so I started playing with the receive connector setting it up with the IP of that client machine and marking it as Exchange Servers in the Permission Groups and setting the authentication to Externally Secured. This still doesn't allow him to send emails. He can't even telnet to any of his outgoing servers from his machine while I can do it from the server just fine.
    Any suggestions please?

        It isn't clear what the POP3 accounts are pointing at. Exchange or other external accounts.

        When it comes to POP3, the configuration can vary widely. Some ISPs will allow access to their SMTP server for sending email, others will not. Some ISPs will block access to other SMTP servers and force users to use theirs. It isn't something I recommend for roaming users unless they have a VPN connection back to the home office and a private SMTP server because of the hassles with getting it to work reliably.

          They're indeed pointing to that users ISP's smtp server. While at home he VPNs to the office but when at the office he can't connect to his ISP which would mean something is no allowing him to do that and I don't know what it is. As I said before I have no problems telneting to his ISP on 25 directly from the server but when I do it his PC while he's at the office it won't even connect.

            I'd say the most likely problem is that his ISP is rejecting his attempt to relay.


            Why not consider the following:

            create two Outlook profiles. One for his POP3 accounts, and one for his Exchange account.
            Then he can just switch between them when he starts outlook

              I found that the router is set up to block 25 from anything other than the server.

                  Tehcamel, I started with setting him up with a separate profile till he decided that he needs access to his other accounts and to be able to reply from those accounts while at the office.

                    ahh.. see now though, you can say "actually i've just found out that company security policy dictates that only the server is allowed to connect onto the internet across mail protocols."

                    unless of course, he's rthe MD or similar...

                      That is how I have all of my sites configured - port 25 blocked.
                      This will stop any compromised machines from sending out spam email and getting the IP address blacklisted. That is the most common cause of blacklisting and can have a significant impact on the business.
