Anybody pls help. We have e2k server on w2k with all updates and patches. This server is put under firewall in ISP's premises. Their responsibility ends there. They dont and cant provide any other support. Now the issue is our server is listed as open relay server in some sites like njabl.org and mails are not going to some domains which use these lists. Our mail server is accessed thru leased lines, ISDN and dialups throughout the country and clients are OWA and outlook express( POP3, IMAP & OWA clients). I have gone thru the KB articles for closing Open relay but i guess people who are accessing thru dialup will have problems if I follow those steps and list the allowed IP adderesses. Any other way that I can address this issue. Pls suggest.
Thanks in advance
