Email auto-replies?

How we can avoid this?

Do mailing lists manage to avoid this? I am pretty sure they also get hit with these. On the web end of things we can certainly just take them down.

I think we might be able to avoid this by changing the ‘return-path’ header (and possibly the ‘from’ header) on outgoing emails.

I think on mailing lists the “To:” header is the mailing list email so the client just send out of office replies if an email has the person email in “To:” field, not a mailing list one.

This is what I found:
