RE: [IMail Forum] Slightly OT: IP vs Name Based Hosting -- PTR ramifications?

[CyberSharks.Net Support Team]

Same here…We have thousands of domains and a single PTR record that points to the OHN of the Imail server. No real problems with any other mail servers that I am aware of.   Justin Dixon, CCNA CyberSharks.Net, Inc. http://www.cybersharks.net     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Grant Griffith - IMail Sent: Thursday, June 30, 2005 2:31 PM To: IMail_Forum@list.ipswitch.com Subject: RE: [IMail Forum] Slightly OT: IP vs Name Based Hosting -- PTR ramifications?   Hey Chris,   We currently have around 200 domains using the same IP and have never had an issue with AOL or anything else.  We just have the PTR setup as the OHN Imail uses for that IP.  I would say you will not run into any issues as long as no other small ISP’s in your area  require the PTR to match.  But if they do they will have problems receiving mail from many other places as well.   Thanks, Grant Griffith EI8HTLEGS, A Division of ETC (812)932-1000 From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chris Anton Sent: Thursday, June 30, 2005 1:04 PM To: IMail_Forum@list.ipswitch.com Subject: [IMail Forum] Slightly OT: IP vs Name Based Hosting -- PTR ramifications?   Howdy All, We are currently configured with IP Based hosting for our 250 websites and are considering a move to Name based hosting to save money ($2 per ip per month = $6000 per year).  We currently have unique PTR records set up for each IP corresponding to the domain name of that IP.  Are there any email ramifications with configuring 200 sites hosted on 1 ip which only has 1 generic PTR record? (Looking to avoid 200 PTR records on that one IP... don't want to disclose all my domain names in one PTR lookup!).  Our clients send via our Imail server and it acts as a relay for the web servers.  I am particularly concerned about spam filters by AOL, et al.  AOL claims that the PTR does not have to match the A record, but is this true for others too???  Am I setting myself up for trouble? Thanks for the help!
