[OT] Two suggestions on list management...

[derby]

Has anyone else noticed an increase in Spam?   I set up an alias derby@<mydomain>.com which is now getting a ton of stock spams from ‘bots.   The e-mail alias is only used for this list and I’m certain that its coming from an archive site.   It would be nice if the e-mail addresses were munged prior to being placed on the archive site.   Also, it would be nice to have a clear filter in the subject line to indicate where this mail is coming from.   For example, the Dovecot mailing list will include inject a [dovecot] tag in to the subject line. This makes it easier to filter the mail and put it automatically in to the correct mbox. It will also make it easier to filter against the alias. So that any mail to derby@<mydomain>.com that doesn’t have a tag like [derby-user] will automatically hit /dev/null.   Can this be done?   Danke!   -G
