Hello all, |
| 2 |
|
| 3 |
Probably the sendmail-list would be the better place for this rant |
| 4 |
but I think I'll check with you guys first, just to see whether or not |
| 5 |
I've missed something obvious. |
| 6 |
|
| 7 |
I'm trying to get sendmail to work properly on my laptop. It's forwarding |
| 8 |
all mail to the smarthost `mail.gmx.net' [1]. That's a free German |
| 9 |
service - and I'm considering leaving it looking at the trouble they're |
| 10 |
causing... |
| 11 |
|
| 12 |
Now first of all, I'm using a dial-up connection (ADSL PPPoE) - So my IP |
| 13 |
adresses are changing on a regular basis and I'm not registered with any |
| 14 |
dynamic DNS-service. I don't have a FDQN and I don't want/need one, do I? |
| 15 |
/etc/conf.d/hostname contains just `HOSTNAME="mymachine"', where `mymachine' |
| 16 |
is how I called my machine. I did not set te domain name. Is there a |
| 17 |
reason I should? So /etc/hosts just contains |
| 18 |
|
| 19 |
127.0.0.1 localhost mymachine |
| 20 |
::1 localhost |
| 21 |
|
| 22 |
Fair enough. But sendmail does not like this setup. When starting it via |
| 23 |
the init scripts it lags seriously and checking the logs gives: |
| 24 |
|
| 25 |
Jul 16 02:06:14 [sendmail] My unqualified host name (localhost) unknown; sleeping for retry |
| 26 |
Jul 16 02:07:14 [sendmail] unable to qualify my own domain name (localhost) -- using short name |
| 27 |
|
| 28 |
... repeatedly. Whether or not I set HOSTNAME to be some |
| 29 |
$phantasy_value or just `localhost' does not make any difference. |
| 30 |
BUT if I set my hostname to something as stupid as |
| 31 |
`mymachine.foo' (LITERAL `foo') _or even_ just `mymachine.' sendmail stops |
| 32 |
to complain and starts immediately (Yes, I restarted /etc/init.d/hostname). |
| 33 |
What's the deal? |
| 34 |
Why this stupid behaviour? Why does it want to have a `.' in the |
| 35 |
hostname - why do I have to trick it so that it thinks it has a domain |
| 36 |
where in reality it does not? |
| 37 |
|
| 38 |
Anyways, now with sendmail up and running, I want to send e-mails. Alas, |
| 39 |
it seems impossible. Sendmail seems to ignore 50% of its configuration |
| 40 |
files. First of all, you might notice the X-Authentication-Warning |
| 41 |
flag in this email's header. Well, for mail.gmx.net to accept an e-mail |
| 42 |
I have to invoke sendmail with the `-fmyemailaddress@×××.de' flag, wich |
| 43 |
causes sendmail to add this header for obvious anti-spamming reasons. |
| 44 |
That's fine and sendmail seems to offer a mechanism which can circumvent |
| 45 |
the printing of this warning to the message's headers: trusted users. So |
| 46 |
I add my user to trusted useres using this directive in sendmail.mc |
| 47 |
|
| 48 |
define(`confTRUSTED_USERS', `me')dnl |
| 49 |
|
| 50 |
rebuild sendmail.cf, restart sendmail and - nothing happens. I tried |
| 51 |
different mechanisms, for example /etc/mail/trusted-users and the |
| 52 |
according directives. To no avail. Sendmail ignores them all. |
| 53 |
|
| 54 |
Without the `-fsomeemailaddress' flag, I can't send any e-mail at all |
| 55 |
because mail.gmx.net will give me only negative responses like `Service |
| 56 |
unavailable' and a message which says something like `this server does |
| 57 |
not accept empty envelopes from'. It stops after the `from' leaving the |
| 58 |
whole sentence ungrammatical... |
| 59 |
|
| 60 |
What am I doing wrong? I'll give you my sendmail.mc in |
| 61 |
case it helps: |

I have tried /various/ configurations and read _a lot_ of docs most of |
| 87 |
the relevant sections of O'Reillys sendmail book. I did not find my |
| 88 |
mistake so far. There are two issues to be resolved and they are |
| 89 |
independant: |
| 90 |
|
| 91 |
1) Why does sendmail ignore me as a trusted user? If I execute mutt as |
| 92 |
root and send the e-mail it does not issue an x-auth warning |
| 93 |
2) What's wrong with all those domains? |
| 94 |
|
| 95 |
I'll appreciate even _reading_ through this lenghty mail, let alone |
| 96 |
_answering_ - so thanks to anybody willing to help |
| 97 |
|
| 98 |
Yours, |
| 99 |

| 101 |
P.S. while writing the e-mail I've already concluded that I'll just |
| 102 |
leave the domains as they are and use the `-f' switch, but only with |
| 103 |
`-faleks_d', because I don't have the e-mail address `aleks@×××.de', but |
| 104 |
that's my username on _my_ machine. So the most pressing issue is to let |
| 105 |
sendmail send mail that does not include this ugly |
| 106 |
X-Authentication-Warning header. It's really ugly, you must admit ;-) |
| 107 |

[1] but it's qmail, how can it be smart then? ... :-P |
