When we connect to a IRC Server we get a lot of messages

We get these messages on every connect, so multiple times a day if you are on a laptop and regulary lose connection.

This accumulates in MAM to thousands of messages which i would argue are not relevant later.

the no-store hint would tell MAM to not store these messages

Another solution would be to make the message type=headline, which also would exclude them from MAM

Example:
