Ok, here is where Im at now. Ive disabled TLS altogther for the moment to work my sasl problems. From a remote site with Kmail config'd to use smtp auth, Ive got encryption set to none and plain. Here is what I get:

The server responded: "<my@email.com>: Recipient address rejected: Relay access denied "

Is it possible to extend the current guide (or tell me how) to actually make the server a fully fledged mail server?

It's working awesome at the moment, the local server is d'l the messages without a problem, the workstations d'l the email from the local server and they also send through the local server, which then forwards it to my ISP.

How can I extend this to make my local server an actually mail server which can by itself accept emails for the local box?

Proteus · Posted: Tue Jul 15, 2003 4:06 pm Post subject:

I would assume (someone has previously stated such behaviour in this thread) that the server is already capable of receiving mail by itself. All you need is a valid MX-DNS-record. Some dyn-ip services offer it, I believe.

I am not sure how one can change the server's behaviour to not use you isp's smtp server, however.

I, too, would like to know a lot more about postfix as a full-fledged mail server. But tutorials/docu for that stuff is either hard to find or hard to understand or both...

I got it working as a "fully fledged Mail server".

Today I spent time configuring my DNS and getting it going. Setup my MX record and everything in BIND, then I tried to send an email to myself (bangers@mail.home.threeten.com) and it was rejected. "recipient is myself" error.

So I added mail.home.threeten.com into mydestination variable in main.cf, and it has worked fine!

Cheers

Great that you made it working!

This is almost working perfectly for me, bravo! My only problem comes when I try to access my IMAP server via Outlook Express. I get the following error:
"PLAIN authentication failed. None of the authentication methods supported by your IMAP server (if any) are supported on this computer." -- yet Thunderbird under Win works fine.

So I'm unsure as to where I'm going wrong. Could someone point me in the right directoin?

Dudes, excellent guides, one and all.

Beowulf:

The main guide was very helpful. It took me several tries to get things goin, and I'm still trying to make sure that fetchmail and procmail are doing what I want. But the squirrelmail part went up without a hitch, as did the courier-imap part, and the postfix (I had tried several times in the past to get postfix going, to no avail).

Chris:

I have high hopes for the bogomail thing...it looks like it works, I just haven't received any spam to check it with yet!

Proteus:

Same to you. Everything appears to be working fine, it's just a matter of time before I train all the spamfilters (and I get tons of SPAM, so that shouldn't take too long.

-----
A few suggestions:

It might be worth while to spend some time constructing different examples for the main guide. I found myself scratching my head several times to figure out which username I should use for which setting (since mine are all different, and yours are all the same), but eventually I think I got it figured out.

I had one or two more, but my brain is mush, so I'll post them later if I think of them.

Still, it is an excellent guide, and following it very carefully, works fine for me (like I said, I think I broke procmail and fetchmail, but I can't think too hard right now so I'll have at it again later, and post the results).

I'm still trying to get mail sending to work, but I'm in a somewhat different situation.

My workstation connects to the net through a router box running slackware (my goal is to replicate this setup on that box as soon as I can figure out how), so I naturally did everything on my gentoo box, but that made some things weird, what with the hostname config and all. I think I've got that ironed out, once I made sure to forward the appropriate ports through the firewall to my box.

The only flaw in my setup now is that I have to use Windows XP several times a week to work with high-powered (and high cost) audio apps for which I haven't found Linux equivalents. I want to be careful that I don't get important mail stranded between OSes, so if I can get the imap thing w/ fetchmail going on the router box (so I can access it in either linux or windows, or from any outside host (eg at work)) I will be a *VERY* happy camper.

But this guide will be indispensible in that venture, I think, because of the excellent configuration file walk throughs.

Once again, thank you.

Skal!

OK, so I feel pretty dumb.
The reason that procmail/fetchmail wasn't working was that I had a type on my .procmailrc.

Oh yeah, and I forgot to turn on cron.

Anyway, the receiving seems to be going good now, and I'm training the filters, so they should start kicking in (they add their tags to the message headers, they just don't know about spam yet) soon.

Now it's just the outgoing mail (and hopefully, after that, receiving mail locally from outside). Hopefully it'll be as simple and stupid as the above, but not likely. We'll see.

Good luck.

Skal!

Hey man,

Thanks for posting here, and those suggestions I'm sure won't have fallen on deaf ears *pokes beowulf*.

Personally, I've used this guide to install 4 actual mailservers (i.e. central servers) for households with 4 and greater people. Great work!

Hi,

all works fine since a lot of time working on the mailserver ... instead of sending mails.

Mails will be send fine, but not bounced through my internet smtp server.

This is a spamassassin-header from my own mails sent to myself:

Help me please, all of a sudden my IMAP server does not recognize my system username and/or password. AFAIK I have not changed any conf files or anything. I have tried to restart courier-imap-ssl and authdaemond, to no avail. What can I do?

Hi,

I'm having a few problems with stage 3.3:

peje · Tux's lil' helper Joined: 11 Jan 2003 Posts: 100

First tanx for this howto. I can't get bogofilter to work.
When I want to run bogotrainer I just get:

bash-2.05b# su peje
bash-2.05b$ ~/bin/bogotrainer
File "/home/peje/bin/bogotrainer", line 15
if dir[len(maildir):len(maildir) + 5] == ".Spam":
^
IndentationError: expected an indented block
bash-2.05b$

Any hints?

Guys, I'm not perfectly clear on this after reading all the thread so I'll ask.

I have my own domain and I don't want to relay to my ISP's smtp server but to send it directly from my box. I still want to be able to authenticate from outside my network. How does that affects steps 3.2, 3.3 and 3.4?

Thanks for the documentation. I must admit, that I haven't tried it yet, & I did find much of this very confusing, but we'll have to see how it works.

I suggest that some people go through the entire thread, & edit out any redundant material. I find that it is very difficult to read through 7 pages.

Brilliant guide!!

I managed to get some basic functionality working, I can connect to imaps, I can send mail through postfix unencrypted. But I can't get the TLS to work. At first the logs indicated there was something wrong with my certificates, I made sure all the entries were present (country, location etc), now that messages doesn't come up anymore. Instead I get this:

The tip that seems to be missing from this configuration guide for a home email server is how to sync your local system names with the email address your isp provides. There are many occasions where you may want to use a different account name on your local server than the email name your isp uses. You can configure this in the email client settings... but that may require configuring several user applications. There's a simple config change you can make to postfix.

http://www.postfix.org/rewrite.html
Reference the Canonical address mapping

an entry like
localuser@localdomain luser@isp.com

for each of your home users, will automatically rewrite the outgoing addresses. Other MTA's like sendmail and exim also support this feature, although the setup is different.

I have the same problem as Weejoker:

Well...it's been a long day. I got sasl to work, but it was completely by accident. The guide here wasn't getting me completely up and running so I went googling and found this more detailed guide http://postfix.state-of-mind.de/patrick.koetter/smtpauth/index.html. I left all the stuff installed like beowulf instructed, but basically started following the instructions for configs from this other howto. I stopped getting "no secret in database" errors and progressed on to getting
