How can I verify if there is a problem at my end?   Thanks!!!

You can try sending me a private message as well. My server will not except traffic without a reverse record. Though it should be child's play for the ISP to configure - usually just one entry, maybe two depending on the version of UNIX BIND they are running. If you use dnsstuff.com's top middle colum spam database lookup, it will indicate what your PTR is or isn't. The CBLs and DBNS may or may not have you listed depending on the amount of email you have sent or if anyone has complained so that too makes sense. I just ran into this problem with someone in the same building. Really, this is pretty simple to fix once everything is in place. Good luck and let know how things turn out.

This is the possible reason I think.   What should I do in this case as this will take some time to get it setup. Can I use any other smtp server and how?   DNS Stuff doesn’t show my in BL.   I am able to telnet the other server but not able to do helo   it gives unrecognized command reply (500 #5.5.1 command not recognized).   Thanks!!!
