I have honestly searched and have tried several of the options that were given in previous questions posted here but can't seem to get my email server to send mail to some email addresses like AOL, twcny.rr.com and about 10 other domains. Messages continually queue up, but do not get sent. We are running Windows 2003 standard with Exchange 2003 and a Pix515e as our firewall.
I am also recieving NDR's with the following error "This message was rejected due to the current administrative policy by the destination server".
I have checked RDNS, we are not using dynamic addressing and we are not blacklisted or on the spam list.
About the only thing I am not able to do on some of the recommendations is to telnet from within my network to AOL or some other mail servers. What occurs is I receive the 220 then a whole bunch of dots appear and thats about it, I get a blinking cursor and when I type helo or ehlo I receive 500.3.3 Unrecognized command.
I greatly appreciate any assistance you can provide me.
