Spam filters are usually your best friend since more than 50% of e-mail in 2017 was spam.

Sometimes however the spam filters that are meant to protect us will turn against us. Sometimes there are valid reason for them to do so, especially if you recently sent one (or more) mass mailing that was not well received by the audience you sent it to.

You might however not be the only one sending mail using your domain. Spammers can use different techniques to abuse the authority your domain has built to their advantage. It is for this exact reason that you should be configuring your domain and mail servers correctly.

Hi, my name is Jorgen Evens for the people that know me I’m usually “the IT guy”. My daytime job makes me a software developer, and after hours I’m the sysadmin for some local businesses and a consultant on projects that link software and tools to the infrastructure that runs them.
