InfoWorld articles

Posted on by

Today I discovered InfoWorld with these articles:

And a bonus article from Spotify: How We Use Golden Paths to Solve Fragmentation in Our Software Ecosystem .
Also, I should note, I very much like the InfoWorld URL format: https://www.infoworld.com/article/3614850/no-one-wants-to-manage-kubernetes-anymore.html — this is the same URL structure I use in my own designs.

dovecot IMAP not working on iOS because of Let’s Encrypt certificate problem

Posted on by

So I was having an issue with the mail app in my iPhones not being able to get IMAP email from my dovecot server.
Turned out I needed to change my dovecot config from this:

ssl_key = </etc/dovecot/mail.{{ domain }}.key
ssl_cert = </etc/dovecot/mail.{{ domain }}.crt
ssl_ca = </etc/dovecot/mail.{{ domain }}.chain.pem

to this:

ssl_key = </etc/dovecot/mail.{{ domain }}.key
ssl_cert = </etc/dovecot/mail.{{ domain }}.chain.pem
