at all. There’s no mail or anything relayed through it other than it being the gateway. Thank you, Steffan Cline 602-793-0014

Re: Postfix 3.x for RedHat/CentOS 7.x

Steve, Any chance you’d consider making a repo for your builds? Although I know I can build from source, I’m a bigger fan of yum and repos. I can even host it if you’d like. Thanks, Steffan Cline stef...@hldns.com 602-793–0014 From: on behalf of Steve Jenkins Date: Saturday, September 5

Re: Stan Hoeppner's fqrdns.pcre file?

I have it on good authority that he is still in Missouri but is absent due to a personal nature. I will share more if allowed in time. In the interim, I've been checking to see if I can get his domain back up for everyone again. Thanks, Steffan > On May 6, 2015, at 8:21 AM, B

Re: TLS Issue

sure where those configs from dovecot comes into play when it's postfix showing the error. Do Viktor's suggested dovecot configs also pertain to postfix? I'm still checking on the TLS implementation of the middleware for my webapp that sends the email.

;From the options I see, I could put that into the startup file above by changing: OPTIONS="--unix=$SOCKET" To OPTIONS="--inet=127.0.0.1:6" My question now lies in do I need to add any any additional config to master.cf file to take advantage of this service? Thanks

Spam filtering

ne spot, I saw mention that it is not needed. Which is it? Is it worth it? I have postgrey installed via yum. Does anyone know how to make all this work? It seems it would be optimal setup for spam prevention. It's a long post. Sorry.
