Between Sunday night and Monday night, my power was off for 18 hours. This took my mail server offline. Nothing should have bounced, but if you sent me mail, you may have received a warning about it being delayed.
Last night around 4am, the power went off again, and it's still off. The NStar ETA for having it fixed has been pushed back 3 times already. I'm considering rerouting my mail, but in the meantime the johns at gnu.org address is still working.
Update: Power seems to be restored, email is working again.
