Re: PDF attachment converting to Base64 plain text

Well, this gives me something to work with. I'll sign up for Zoom and run some tests. I don't have an O365 tenant, but maybe we can start here and see what may be happening.

Re: PDF attachment converting to Base64 plain text

I did see where someone mentioned that releasing the mail from the UI leaves it intact, maybe this would be a way to capture one? Release it and get me a a raw copy with headers?

Re: Use NAMED instead of UNBOUND for DNS

In the next update I'm going to separate the eFa-Monitor cron config and code so that we don't touch the monitor items entries. You will need to modify it one more time after this is done, so just be prepared for that.

Re: Use NAMED instead of UNBOUND for DNS
