First, email messages sent by the trac ticket system require moderator approval. This didn't used to happen, but I don't remember when this started.  As the moderator, I respond and the message is sent.  That's not great, but I don't mind it because there are very few tickets.

However, within the last month or two, when I respond to the moderator message, I get a bounce saying the email couldn't be delivered to the reply address.  It's something like cmucl-ticket+moderate-2b6c59a112760eb7@common-lisp.net, where the hex digits change with each message. This didn't used to happen.

The ticket message is, however, successfully sent.

These are just minor annoyances that didn't used to happen.
