Every time I post to the fedora lists lately, I am getting an autoresponder antispam message back from one of the list members:
eorgan945.sspam@uol.com.br
This is completely irresponsible behaviour, and bad netiquette.
The way I see it, there are 3 choices:
1) This person immediately disables this antispam confirmation bot and apologizes to the mailing list(s), promising to never do this again.
or
2) The list administrators kindly remove the person's address from the subscription list, transfering it to the permanent ban list. If necessary, blocking the entire domain if the problem returns (uol.com.br).
or
3) I for one, will unsubscribe from all of the fedora lists, simply to avoid this nonesense. I get 300 spam per day, and certainly don't need someone adding to it foolishly on subscription-only mailing lists.
If #2 becomes necessary, and the individual can not be identified, I suggest blocking uol.com.br at the IP filter level on Red Hat border routers.
