What IP Blocks does iContact use

What IP Blocks does iContact use

Sep 11, 2013 by Paul White

Recently I had to whitelist the IP blocks from iContact to ensure their newsletters would get through to my clients.  I had to directly contact iContact to get their IP Blocks, of which they gladly gave me.  I rarely see spam coming off their servers so I felt it was safe to whitelist them on my mail server.

How to get into Yahoo Inbox with your bulk emails

Feb 21, 2010 by Paul White

yahoo inboxYahoo runs one of the strictest Anti Spam setups of all the Free mail Servers.  If you send any kind of bulk emails then you likely haven't had much success getting into the inbox of yahoo.  Your Emails are either bounced with a deferred message like this Reason: Remote host said: 421 4.7.0 TS01 Messages from 69.80.230.7 temporarily deferred due to user complaints - 4.16.55.1. or they end up in the spam folder.  After switching IPs of my mail server I had the opportunity to validate many of my theories on how Yahoo's AntiSpam technology works.

ATT and Verizon DNSBL Problems.

Feb 13, 2010 by Paul White

Verizon and AT&T yesterday started bounced emails from my server.  This was very unexpected, as non of my websites do any kind of spam.  A few of them do send a newsletter but this is to a double Opt in Maillist.  Everyone getting the newsletter signed up for it.  So in this blog I will chronicle my journey to get this resolved with both ISPs.  If this turns out good, then fine. If it turns out bad, then at least I will have documented it for the rest of the world.

How to increase your open rates for your bulk emails

Nov 14, 2009 by Paul White

If you are are like me you have a strong belief that if you want it done right you have to do it yourself.  Running a Mail Server that sends any kind of bulk emails brings many issues that noobie Server Admins don't have a clue about.  I found there wasn't much information about how to properly run a mail server so I thought I would write a complete blog on the issue.  So if you want to greatly increase your open rates, read this
