esa-l -- Email Sanitizer announcements


About esa-l
English (USA)

A low-volume list for announcements of Sanitizer updates and other news, and occasional announcements of general email security alerts (such as the discovery of a new attack vector).

This is not a discussion list. Please see the esd-l list for discussion.

If you are using a challenge-response email authentication tool, PLEASE remember to whitelist the appropriate email addresses - it is very annoying for the list owner to start getting demands for proof of identity after someone subscribes themselves.

Sites that repeatedly spam this list or its administrative addresses will be tarpitted, and I will laugh maniacally.

To see the collection of prior postings to the list, visit the esa-l Archives.
