| 41 | ## Restrict users to plausible envelope sender addresses. This is | |
| 42 | ## surprisingly fiddly. What I actually want to say is that the local part | |
| 43 | ## must match ^$sender_ident(\$|-) and the domain part must match an | |
| 44 | ## appropriate domain; but writing a conjunction is rather tricky. And so we | |
| 45 | ## must burn some addresslist variables. | |
