I'm teaching and speaking at BSDCan this year. I'm reprising my "OpenSMTPD for the Real World" tutorial, updated to take into account recent changes to OpenSMTPD. I'm also giving a new talk "Road Warrior Disaster Recovery".
I'm also moderating the Amateur Radio and SDR BOF.
I'll post a link to the schedule when it's up on the BSDCan website.
The schedule is up for the tutorial, talk, and bof.
