Return-Path header field is introduced by the MTA when it receives the |
| 11 |
mail from the other party. The protocol is like this: |
| 12 |
|
| 13 |
... |
| 14 |
mail from: mrness@××××××.ro |
| 15 |
250 Ok |
| 16 |
rcpt to: mrness@g.o |
| 17 |
250 Ok |
| 18 |
data |
| 19 |
354 End data with <CR><LF>.<CR><LF> |

Here you have mrness@××××××.ro as Return-Path. Please note the fact that |
| 31 |
submitted message does not have such field yet and even if it had, it |
| 32 |
would be overridden by the MTA with what I specified in "mail from:" |
| 33 |
command. |
| 34 |
Because I used telnet, I was able to specify 2 different addresses for |
| 35 |
the From and Return-Path addresses, but all the MUAs I worked with have |
| 36 |
no such fine grained settings. For Thunderbird, when I say I want to |
| 37 |
send mail as joe@×××××××.org, the same address will go also in the |
| 38 |
Return-Path. |
