Hello All,
I need some insight here. I recently moved my Imail/DNS to a new server and all has been running quite well. I did have one customer whose DNS records got screwed up so I rebuild his domain records and ran a DNSReport using dnsstiff.com against my server. One of the errors I saw was related to recursion, in that my DNS is an “Open DNS”. OK. The report explained the bad things that can happen and suggested I turn recursion off. Dummy me, I did. I get a call this morning that no one on my hosted mail server received any email last night from outside sources. I went an turn on recursion and all is working again.
My questions:
1) If having recursion is a “bad” thing, how do I disable recursion without disabling my users from getting their email? Remember this is a hosted server and I have users all over the country accessing it. I know I can set specific networks/subnets to use it but how can I possibly specify every network that will access the email?
2) Since no one received any emails, where are they? Did they bounce back to the senders or are they simply gone forever?
Thanks for any insight.
