I am having a problem with an e-mail account using POP3. This account works fine on many computers and ISP's using Outlook XP. However, when trying to use the account with Outlook XP on one particular computer accessing the internet via AOL dial-up, I get the following error upon trying to send a mail (receiving works fine): 550.5.7.1 <email@address.com> ... Relaying denied. IP name lookup failed [insert currently assigned IP address here] Other POP3 accounts in Outlook on this computer have the same problem. It seems to me that this may be a problem with AOL dial-up, however, I have used POP3 e-mail accounts with an AOL dial-up connection before (just different computers) and it worked fine. Any suggestions??? Any help would be greatly appreciated.

Found these in the MSKB: This one deals with this error: Server Response: '550 <someone@microsoft.com>... Relaying Denied', Port: 25, Secure (SSL): No, Server Error: 550, Error Number: 0x800CCC79 http://support.microsoft.com/default.aspx?scid=kb;en-us;223477&Product=out#6 http://support.microsoft.com/default.aspx?scid=kb;en-us;296408&Product=ol2002 http://support.microsoft.com/default.aspx?scid=kb;en-us;281605&Product=out2003 Please post back and let me know if these help...
