Yes, basically you can just invoke 'sendmail box@××××××.etc' and type |
| 12 |
message with all the headers you need - 'to:', 'from:', 'subject:' etc |
| 13 |
to stdin. |
| 14 |
Of course, every language has some wrappers to simplify that process. |

Not really. |

Your IP belongs to an ISP, and it's DNS server has the authority for |
| 21 |
that address. So, if anyone (e.g. mail server) is asking any (other) DNS |
| 22 |
server "who's that guy?", that DNS will go to your provider's DNS and |
| 23 |
ask "so, it's one of yours, who is it?" and it'll be in position to |
| 24 |
either return some valid name (that's rarely free), delegate the task |
| 25 |
to some other DNS (mostly the case with IP ranges, bought by some |
| 26 |
organizations) or just shrug, which is often the case with common users. |
| 27 |
|
| 28 |
So the answer is likely - "it won't matter, you won't get a name", but |
| 29 |
that's entirely up to your ISP. |
| 30 |
|
| 31 |
That said, there are always possibilities to use the services of (or set |
| 32 |
up) some relay server or buy dedicated IP and tunnel traffic through |
| 33 |
it, but that's quite beyond the scope of question, I believe. |
