Having Trouble Sending Emails to Yahoo or AOL?

Noticed your emails to friends with Yahoo or AOL addresses are vanishing into the digital abyss? You're not alone, and it's not your fault. A bit of a hiccup with Microsoft's Exchange Online and some new, stricter security measures from Yahoo and AOL are to blame.

Around the end of February, Exchange Online users started facing issues sending emails to Yahoo and AOL accounts. Microsoft spotted the problem and identified it was due to some of their email IP addresses getting blocked because of new rules by AOL and Yahoo aimed at stopping spam.

They're on it, though, working with a spam-fighting partner to sort out which IP addresses are causing the fuss.

The issue isn't solved just yet, as per the latest from the NHS in the UK. Microsoft is still in detective mode, isolating the troublesome IP addresses to stop this from happening again in the future. It's a tricky situation because services like Spamhaus are constantly on the lookout for spam, and sometimes even the good guys get caught in the net by mistake.

In the meantime, some savvy users have found workarounds. One user discovered that their emails were getting signed by the wrong domain, fixed it by setting up the correct DomainKeys Identified Mail (DKIM) signature, and presto! Problem solved. DKIM is a security standard that proves an email really came from where it says it did, which helps it get past those strict filters.
