Dammit Microsoft!

I was going through some logs seeing where fail2ban was blocking hosts as recidivist when I stumbled upon an error that didn’t make sense. A host that I more or less expect to receive email from was failing and being blocked when they relayed through Mail gun. Some minor digging found that the errors I was seeing in the logs resulting in a fail2ban rule had to do with the STARTTLS feature. This was written about seven years ago over on warthog9 He links to help pages on Microsoft’s web site about fixing IE, or at least references a broken TLS handshake titled An update that enables Internet Explorer in Windows XP, in Windows Vista, or in Windows Server 2008 to parse fragmented TLS/SSL handshake messages is available

I’m not going to be able to fix Mail gun. I’m not even going to try. The mail eventually gets to us… just slow. But the fix listed does give me insight into something else I ran into this week: broken IE… I’ll try to fix that problem next week.
