Yes I can connect anywhere from this server! There's also running apache, fpt, telnet etc.
And I administrate the server on console from another station, and often i open ftp on this server to download tar gzs like apache, php etc...
Just ask for namend.conf because i wans't sure about it. but when I do it manually by nslookup on the solaris box. I get all mx result diffrent hosts.
tryout for berlin.de
nslookup
> set quertype=mx
> berlin.de
Server: ns02.ch.abatos.com
Address: 143.99.32.11
Nicht-autorisierte Antwort:
berlin.de MX preference = 100, mail exchanger = zeus.nic.dtag.de
berlin.de MX preference = 10, mail exchanger = mx0.berlin.de
zeus.nic.dtag.de internet address = 194.25.1.124
mx0.berlin.de internet address = 195.243.105.32
so the dns resolver works...
also could I send Mails to my server via smtp... but it's belin.de like my nslookup example. I get a postmaster message that it could find the host, but by nslookup, on the same server... it find the host!!! There's a brocken pipe between sendmail and dns resolving... im a bit confused about that!
So I don't know what I do wrong. And I'm not new to unix. So where are additional config for sendmail to dns resolv. I don't find more than sendmail.cf resolving entrie.
thank you!
.... i dont really what's wrong.

EXPN(1) General Commands Manual EXPN(1)
NAME
expn - recursively expand mail aliases
SYNOPSIS
expn [-a] [-v] [-w] [-d] [-1] user[@hostname] [user[@hostname]]...
DESCRIPTION
expn will use the SMTP expn and vrfy commands to expand mail aliases. It will first look up the addresses you provide on the command line.
If those expand into addresses on other systems, it will connect to the other systems and expand again. It will keep doing this until no
further expansion is possible.
OPTIONS
The default output of expn can contain many lines which are not valid email addresses. With the -aa flag, only expansions that result in
legal addresses are used. Since many mailing lists have an illegal address or two, the single -a, address, flag specifies that a few ille-
gal addresses can be mixed into the results. More -a flags vary the ratio. Read the source to track down the formula. With the -a
option, you should be able to construct a new mailing list out of an existing one.
If you wish to limit the number of levels deep that expn will recurse as it traces addresses, use the -1 option. For each -1 another level
will be traversed. So, -111 will traverse no more than three levels deep.
The normal mode of operation for expn is to do all of its work silently. The following options make it more verbose. It is not necessary
to make it verbose to see what it is doing because as it works, it changes its argv[0] variable to reflect its current activity. To see
how it is expanding things, the -v, verbose, flag will cause expn to show each address before and after translation as it works. The -w,
watch, flag will cause expn to show you its conversations with the mail daemons. Finally, the -d, debug, flag will expose many of the
inner workings so that it is possible to eliminate bugs.
ENVIRONMENT
No environment variables are used.
FILES
/tmp/expn$$ temporary file used as input to nslookup.
SEE ALSO
aliases(5), sendmail(8), nslookup(8), RFC 823, and RFC 1123.
BUGS
Not all mail daemons will implement expn or vrfy. It is not possible to verify addresses that are served by such daemons.
When attempting to connect to a system to verify an address, expn only tries one IP address. Most mail daemons will try harder.
It is assumed that you are running domain names and that the nslookup(8) program is available. If not, expn will not be able to verify
many addresses. It will also pause for a long time unless you change the code where it says $have_nslookup = 1 to read $have_nslookup = 0.
Lastly, expn does not handle every valid address. If you have an example, please submit a bug report.
CREDITS
In 1986 or so, Jon Broome wrote a program of the same name that did about the same thing. It has since suffered bit rot and Jon Broome has
dropped off the face of the earth! (Jon, if you are out there, drop me a line)
AVAILABILITY
The latest version of expn is available through anonymous ftp at ftp://ftp.idiom.com/pub/muir-programs/expn.
