 Posted: Tue Jul 11, 2006 2:33 am Post subject: what would be a good mail server and how to configure it? |
 |
|
I am new to linux, even newer to setting up a mail server. I have a box at home with a DSL and a router running gentoo, and uses homelinux.org to do dynamic DNS. Would it be possible for me to set up a mail server so that I can at least send emails out, and even better to receive emails sent to me@meandmybox.homelinux.org?
I was told that sendmail is a choice, but I am not sure how to set it up. Can someone point me to a good configuration document? Thanks. |

| There is a great guide on how to setup a fully working mail system with a dynamic DNS. Check out the wiki here. The howto comes in two parts and is based on this forum post. I found the howto wiki really a bit too simple, but using the wiki howto and the forum post together is a great way to go. Good luck! |

Great! It is a bit of reading, but I will read it. Is it 100% free? There is some HOW-TO on dynDNS site with a service called mailhop outbound, but it is not free  |

| I am pretty sure it's free. Although to get an MX record you might have to pay, though I doubt it. |

well, here is the deal. I have a box at home uses dyndns, and I would like to install a BBS and a wiki on it, so that a few friends of mine can go there do something. It would be nice if the system is like the real thing and has email notification capabilities, so that when someone sends another a private msg, that person will get notified in email. The problem is, the phpBB favors sendmail. I follow a very very brief cookbook online about how to setup sendmail under gentoo, but I don't think it is working.
so does anyone know if a quick and dirty and free way of accomplishing this task? If not, then I will probably have to disable all the emails. |

You could try postfix, the config files are much easier to understand, and if you only want to send out it's pretty straightforward. And it has sendmail compatibility binaries, so anything that uses sendmail can use it transparently. If you have problems configuring it we are all here  .

I just emerged postfix and configured it according to http://www.postfix.org/BASIC_CONFIGURATION_README.html.
but I can see a pending message sitting in the /var/spool/postfix/active directory not going anywhere.
I use DSL at home, and it connects to a dlink DI604 router. my box sits behind the router. From the BBS, I registered a couple users using gmail address and tested it by mass mailing them. But those messages never showed up in gmail, only sitting in the active directory.
Please help because i believe i didn't do it right |

| You could just give all of your friends a shell accounts and then you could use a local mail system and not worry about the outbound setup. Plus it is always fun to have multiple users on a box! |

I could do that, but isn't it more fun to have email as well? Actually my goal is more of setting up a mail server that could send out emails than anything. |

an update... earlier I forgot to do a newalias, and that's why the email sat in the active directory.. after I did that, restarted postfix, the email got moved to the deferred directory. in defer directory, it seems that it timed out while contacting any of the servers (gmail, hotmail). is this normal? or is this my setup? also, is there a way to have the servers accept my email? |

Hmm it could be any reason. Try pasting the output of
| Code: | | # tail -n 300 /var/log/message | grep postfix |

thanks for sticking with me on this issue. Now I am facing a wierd read timeout problem. I found an article on the Internet telling me how to relay to smtp.gmail.com to send and receive email, using postfix with TLS and SASL, and fetchmail. Since I only care about sending mail, I followed the instructions to have postfix configured. There are some discrepencies because postfix's compilation turned out to be different than what the article says, but I think it went okay.
Later, I found that the artcle assumes gmail smtp server uses port 25, but now it uses 465. So I added the port to where it references smtp.gmail.com. It connects, but kept giving me a read timeout. Could you take a look at what I did wrong and see if there is a way to fix it?
Here is the tutorial article:
http://souptonuts.sourceforge.net/postfix_tutorial.html
My postfix's LD dependency is a little different that the one posted in the tutorial, but I thought it is okay because I am not using keberose at home. below is my ldd
| Code: |
ldd /usr/sbin/postfix
linux-gate.so.1 => (0xffffe000)
libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0xb7f57000)
libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0xb7f25000)
libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0xb7e26000)
libpcre.so.0 => /usr/lib/libpcre.so.0 (0xb7df9000)
libdb-4.2.so => /usr/lib/libdb-4.2.so (0xb7d23000)
libnsl.so.1 => /lib/libnsl.so.1 (0xb7d0e000)
libresolv.so.2 => /lib/libresolv.so.2 (0xb7cfc000)
libc.so.6 => /lib/tls/libc.so.6 (0xb7be3000)

my main.cf below. the tutorial doesn't even mention anything about things like myhostname, mydomain, myorigin, because it was using a fake domain which doesn't exist at all. but I am using a dyndns service, so I have configured all these parameters

contents of my sasl_passwd (of course, I have replaced the actual username and password for security): What I am not sure here is if it is necessary to specify the port number.
| Code: |
[smtp.gmail.com]:465 mygmailusername@gmail.com:mygmailpassword
|
Then I did the following just to match what I have in sasl_passwd (notice the port number is also specified in the key)
| Code: |
postmap -q [smtp.gmail.com]:465 sasl_passwd
|
My generic and transport files started out with only comments from the man page, then I added the following to my generic and transport files:
| Code: |
# GENERIC(5)
root@alpha.sxxxx.homelinux.org mygmailusername@gmail.com
|
| Code: |
# TRANSPORT(5)
gmail.com smtp:[smtp.gmail.com]:465

I noticed the difference because in the tutorial, postconf -n doesn't show anything about myhostname mydomain etc. When I send out an email using sendmail, it would get stuck in the active queue, and eventually get a readtime out and moved to the deferred queueu....

Looks like you've already gone the postfix/phpBB route. However, if it proves too much trouble, Citadel offers private email, public email (BBS), mailing list, and chat functions. I'd have to read through the docs again to see if you can set up email forwarding (email notification capabilities). I'll let you know what I find. I do recall them having instructions on setting up with dyndns. |

Yes, i have already gone that route, because I'd like to learn how to set them up. But just a few minutes ago, I think I completed effed up my email system. Earlier, I noticed a warning in the syslog saying sasl_passwd.db is older than sasl_passwd. So I did a postmap sasl_passwd, and then postmap -q [smtp.gmail.com]:465 sasl_passwd, and restarted the postfix. Now, I can no longer sendmail. The BBS send mail would just hang there. In my syslog messages, i also get sSMTP: Unable to connect to "mail" port 25. WTF? I almost want to throw my box out the window! |
