Re: The hostname in the SMTP greeting does not match the reverse DNS (PTR) record for your mail server.

strange... when i check DNS tools and reverse dns check 52.0.148.79 it tells me that it returns mymodeltalk.com and that this is correct. Why would I need to have a another IP to RDNs from the hostname? I don't want to send mail from it... only from mymodeltalk orinform.mymodeltalk.com. --

Is this a good situation for using masquerading? If not in what situations would one want to use that. -- Mike McKoy *404.590.7176* http://MyForeverHair.com http://www.MyModelTalk.com http://InCrowdUSA.net http://www.google.com/profiles/mikemckoy

Re: Originating Or Sending From Correct Domain IP

OK, then i will research setting up multiple postfix instances. I wonder...is exim better for this? I wanted to use it at first but could not find any documentation of centos & exim. Thanks for the support thus far. It's appreciated. -- Mike McKoy *404.590.7176* http://MyForeverHair

Originating Or Sending From Correct Domain IP

I'm using CENTOS 6.5 I need to configure Postfix to send from the correct IP addresses assigned to each domain. How easy is it to configure postfix to send using a specific IP address for each domain I have on the server? I've already bound the IPs. When I used Exim all I had to do was create a li

Different smtp_helo_name depending on IP version

h. There is value in noticing when a user is sending an unexpectedly large amount of mail, even if you don't use that information to reject. Ratelimiting is a highly useful tool. -- Mike Cardwell https://grepular.com https://emailprivacytester.com OpenPGP Key35BC AF1D 3AA2 1F84 3DC3
