How to deal with the IP Blacklist of Microsoft Outlook

 

In earlier tutorials, I defined how one can simply arrange your individual mail server utilizing iRedMail or Modoboa, and I shared some tips about getting your IP handle faraway from blacklists. Nevertheless, some people have a tough time getting off the Microsoft Outlook IP blacklist, which is utilized by outlook.com, hotmail.com, reside.com, and msn.com mail servers.

Microsoft Outlook usually sends again the next message in case your IP handle is blocked.

As you possibly can see, the entire IP vary is blocked. Personally, I don’t suppose this anti-spam approach needs to be used because of the collateral harm accomplished to reliable senders. In distinction, Gmail is far more clever in dealing with IP fame. You possibly can submit the sender data type to resolve this drawback. Generally Microsoft would unblock your IP handle, typically your request can be refused.

A surefire option to get your IP handle off Outlook blacklist is to get your mail server licensed by Return Path. Nevertheless, that is very costly. It is advisable to pay a one-time $200 software price and at the least $1,375 license price per yr. I’ll present you a free option to bypass the Outlook IP blacklist.

You possibly can configure your mail server to relay emails by way of SMTP relay providers. They keep a great IP fame, so your emails can get via IP blacklists. There are numerous SMTP relay providers. Some cost slightly price, some provide free quotas each month.

You don’t should configure your mail server to relay all emails. I’ll present you find out how to configure your Postfix SMTP server to relay emails which are despatched to outlook.com, hotmail.com, reside.com and msn.com electronic mail addresses, so that you gained’t burn up the free quota shortly.

We will additionally configure Postfix SMTP server to make use of a number of SMTP relay providers. So if one service supplier lets you ship 10,000 emails monthly at no cost, and we use three service suppliers, then we are able to ship 30,000 emails monthly at no cost.

Right here I like to recommend three SMTP Relay Companies:

  • SendPulse: 12,000 emails/month at no cost. No bank card required.
  • SendinBlue: 9,000 emails/month at no cost. No bank card required.
  • Mailjet: 6,000 emails/month at no cost. No bank card required.
