I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1) with apt-get Daemontools and Upstart

Thanks a bunch to Bob and Christopher and everyone else for getting me this far.
I'm still following the "life with qmail" guide on ubuntu server 10.04
So I have the qmail processes up and running, I made symbolic links
from everything in the /usr/bin to /usr/local/bin. This is because I
noticed qmail was looking for other things in the /usr/local/bin like
"softlimit" and so thought this would be safer to do than editing the
scripts.

root [at] themi:/usr/bin# ln -s /usr/bin/* /usr/local/bin

There doesn't seem to be any service errors through any of the
operations I describe in this email although I don't know what the
..... is
root [at] themi:/home/joel/Maildir/new# ps -ef | grep "service errors" |
grep -v grep
root 803 758 0 May30 ? 00:00:00 readproctitle service
errors: ................................................................................................................................................................................................................................................................................................................................................................................................................

After a little bit of messing around I realized I had to create the
Maildir, I found the command somewhere, I think it was this "
/var/qmail/bin/maildirmake" and I finally got the Maildir to work when
I created it with my user account but created the
var/qmail/control/defaultdelivery file with the root account. I have
tested my ability to send messages from my root account to my user
account, but whenever I try to send messages to a remote address I
get:

@400000004c0838b308fb3b84 new msg 5710109
@400000004c0838b308fb4f0c info msg 5710109: bytes 234 from

@400000004c0839df3b56d96c delivery 63: deferral:
Sorry,_I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1)/

I also tried sending it to my yahoo account with the same results. I
tried the test in the qmail handbook for smtp which worked fine:

root [at] themi:/home/joel# telnet 127.0.0.1 25
Trying 127.0.0.1...

Then I tried a test suggested on this thread:
http://www.gossamer-threads.com/lists/qmail/users/126657

From this I noticed that if I tried
root [at] themi:/home/joel/Maildir/new# telnet mx4.mail.yahoo.com 25
Trying 68.142.202.247...
Trying 209.191.88.247...
telnet: Unable to connect to remote host: Connection timed out

I'm thinking that the isp of my server may be blocking port 25. Is
there a way I can find this out for sure, and if so, is there a
workaround for it? Thanks.

This is the problem with 5 year old information, if people don't
know what they are doing.

I cannot contact mx4.mail.yahoo.com on the SMTP port either, probably
due to the fact, that this is no longer listed as a Mail eXchanger
for yahoo.com.

Valid mail exchangers for yahoo.com are:
(dnsmx yahoo.com; dig yahoo.com mx; host -tmx yahoo.com)

yahoo.com. 1642 MX 1 g.mx.mail.yahoo.com.
yahoo.com. 1642 MX 1 h.mx.mail.yahoo.com.
yahoo.com. 1642 MX 1 a.mx.mail.yahoo.com.
yahoo.com. 1642 MX 1 b.mx.mail.yahoo.com.
yahoo.com. 1642 MX 1 c.mx.mail.yahoo.com.
yahoo.com. 1642 MX 1 d.mx.mail.yahoo.com.
yahoo.com. 1642 MX 1 e.mx.mail.yahoo.com.
yahoo.com. 1642 MX 1 f.mx.mail.yahoo.com.

at least for the next 1642 seconds.
Try one of those.

As you don't tell us who the ISP of the server is, how do you
expect us to know if your ISP is blocking port 25 outgoing?
But you can get an easy, fast and probably the most accurate answer
to this question by asking your ISP.

Apologies, I should have looked up more things about mail exchangers.
But anyways I know what the problem is now. I ssh into this server as
it is at my friend's house. I don't know what his isp is (i should
have been clear about this, as I know most people on here haven't read
my previous posts). The real problem is that his router is not set up
to forward port 25. I'll let you know when that is resolved (as he is
currently away and is not able to remote desktop into his computer for
some reason) Thanks.
