I'm having problems sending e-mail to a specific domain, spectra.ca or spectraesolutions.com. Any e-mail to those domains sits in my IMS outbound queue. They can send to me but when I reply I run into the same problem. I've contacted the admin of that domain and he told me they are running Exchange 2000 and they are not requiring reverse DNS lookup. Any thoughts? _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________ Do You Yahoo!?
