I'm struggling with an odd issue and I'm hoping someone can help. I have an old appliance that sends out email notifications via my mail relay running Postfix. The problem is that it is issuing "MAIL FROM: <>", but only part of the time (sometimes there's an email address there, sometimes there isn't). Oddly, they always have a "From" address in the envelope. I'm trying to match the emails that essentially lack an address and rewrite the "MAIL FROM" with a viable default (which would line up with what is in the envelope). And yes, I've tried working with the vendor for months, but I've given up.
The problem is that when these emails eventually hit Gmail, they're rejected -- and for good reason. I tried setting up a sender_canonical_map on my aforementioned server but couldn't get it to work. I then switched from a hash table to pcre and still can't get it to work. What is the most practical way to "fix" these emails so that when Postfix sends them out, they have a viable "MAIL FROM" address?
