I’m sorry to post this here but we are desperately looking for
opinions quickly as this has becoming a real issue to us and I could
not think of any better place to find truly technical mail server folks J
We seem to be having multiple mail servers on multiple networks having
issues sending to yahoo servers for going on 36 hours now
these are a variety of server types on a variety of networks
telnet on port 25 is usually getting this
451 Message temporarily deferred - 4.16.50
keep in mind that some of our servers are having no issues sending mail
any one else having this issue
