I realized the static postfix map we were using locally hadn't been updated in a while, so I generated a new one from git and compared them and discovered that we had made some updates that weren't in the upstream map. I will list them below, but first I think we should consider if there are reasons to still maintain this file over using the SRV method.

• calyx.com moved to v3: kz4bswvhrqufq7e3ntwtco7jwgrpwwmh5j5kvlbonogt7xoipzwfedyd.onion (SRV record still points to the v2)
• calyxinstitute.org moved to v3: kz4bswvhrqufq7e3ntwtco7jwgrpwwmh5j5kvlbonogt7xoipzwfedyd.onion (SRV points to the v3)
• potager.org moved to v3: smsriptlensuwrolqrqp3sqhqpuovc4fg7n2q3l3b6dq3owgrv6c26yd.onion (but no SRV record)
• espora.org v2 record dropped (no SRV, no answer on v2)
• espiv.net moved to v3: jcifdulylocooyez2fh32i53kdo66d7tq7fotdc7lw6r2bgcb3rhjzqd.onion (SRV is CNAME for espiv.net? maybe a wildcard record? doesn't answer?)
• lists.espiv.net moved to v3: zo37k42zdy6n4lw22iamcy46rihir6t7d5imnrxcsyb7vmazvbjej2id.onion (no SRV, doesn't answer?)
• boum.org v2 record dropped (no SRV, no answer on v2)

If these domains want to keep doing onion-mx, make sure you are on v3 and publishing SRV records. Then we can either update the records in the map, or just drop them in the move to SRV only.
