    Hi Geeks,

    My clients are getting Server error 554 5.7.1 relay access denied when they try to send mail to another domain. They are able to receive emails but they are not able to send mail to others.

    I have been looking for this error since last 3 days and I got some information related to this. I read somewhere that it is the cause of not well configuration of Exchange server or somewhere I just read that server might have configured as an open mail relay. Cause of this someone else can enter into exchange server computer and send noncommercial  emails to anybody. They call it Spam.

    I also came across  about it that if any other mail server identify this activity then that server can inform all mail servers and put my exchange server into block list.

    I haven’t a lot of experience about it.

    I am having Exchange server 2003 installed on Microsoft Windows server 2003.

    So, please help me to get rid off this error.

    Thanks in advance!!

    Hi,

    You should first check weather your computer is in block list of exchange server domain or not.
    You can check for this by going through the following links.

    If you find your Exchange server domain in this list then you have to look for solution related to this.

    I think your client isn’t an authenticated user for Exchange server. It considers the person as guest. In this case person can send messages to the internal users but not external users.
    So, firstly your client have to authenticate himself/herself properly to the exchange server, so that server couldn’t consider as a spammer.
