This statement is the source of the confusion surrounding sendmail. |

Internet mail is not complex, it is stunningly simple: |
16 |
|
17 |
mail comes in, |
18 |
look up where it should go, |
19 |
send it there |
20 |
|
21 |
In between you might hand the message off to virus and spam scanners, you |
22 |
might look up an ACL before accepting it coming in, but those are all |
23 |
additives to find valid mail. Remove the additives, and you get the amazingly |
24 |
simple lookup table scheme described above. |
25 |
|
26 |
There isn't even an inherent difference between relays and final destination |
27 |
MTAs, they still send the mail somewhere. The difference is in the viewpoint |
28 |
of the sysadmin. |
