Mail cache bug in Apple Mail using Dovecot

June 7th, 2022

I ran into this bug today with Apple mail and Dovecot/Imap.

I was trying to delete a lot of email and it would go away and then a few seconds come right back. Sometimes it would stick, most times it would come back.

Digging deep into this, I discovered that dovecot creates a mail/.imap cache directory. Looking in the mail logs I noticed that there was a an error about index corruption on the cache.

The simple solution is to stop dovecot, deleted the entire .imap directory and restart dovecot.

This will require the client to re-sync the cache (so it might take awhile if you have a lot of mail or folders).

In my case, this appears to have resolved the problem.

New project on the Horizon

November 1st, 2020

So I am starting a new project. I have decided to start a YouTube channel. My primary focus is going to be on system administration ‘tips and tricks’ and some IT training videos. I will also be doing technology review, how-to videos as well as start doing travel vlogs.

Those of you that know about my previous travel blogs:, it will be a lot like that only video. I have watched hundreds of travel vlogs over the last 3 months and they are all missing things I feel I can bring to the table.

My new website for the channel will be at: and my YouTube channel will be at:

Currently, there is no content. I am in the process of getting my office cleaned up and ready, so I can start recording. I am also testing out a lot of recording equipment and editing software.

If there are subjects or topics you are interested in seeing, please leave me a comment here or on the channel, or send me email.

WordPress App Failure

September 19th, 2020

So I attempted to want to like this app for the Mac, but it last some simple functionality that I use:

  • Adding embedded links causes the app to freeze
  • Categories just don’t show up at all
  • 50% of the times the <save draft> link doesn’t appear.

I will go back to using Safari for now.
