Both should match in that case. > In the mailop life, I saw many sender addresses in header are > different than the envelope addresses. This is the behavior of mailing lists. The MAIL FROM: envelope address will be used for bounces. If you post to a mailing list, you don't want to receive the bounce of subscribers addresses that are undeliverable (e.g. mailbox full, account deleted etc.). > For instance, > 1. use gmail to send email from address other than gmail > 2.

The MAIL FROM will be matched by SPF and that will fail if you relay it to any other external machine that checks it. -- Gruß Marco Send unsolicited bulk mail to 1720201510mu...@cartoonies.org _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
