Hello.
I have a strange problem with my mail system. I'm using postfix (SSL & non-SSL) and courier (POP3/IMAP SSL & non-SSL). The mail is working fine when I use a webmail interface, but it doesn't work with mail clients. I have Outlook Express and each time I want to send/receive mail (regardless whether I use SSL or not) the program shows a pop-up in which it tells me to type in my login (me@mydomain.tld) and my password. I click OK and the data I provided is fine, but the pop-up appears after a few seconds and again prompts me for login data - it goes like this over and over.
Do you know what might cause such a strange behaviour of mail server?

Please advice,
Martini

P.S. This is my postfix main.cf:

the main.cf seems to be very short - normally it has much more lines after the ispcp installation...

Then we have to separate:
is the problem wehn sending mails or wehn receiving?

/J

Martini · 03-15-2011 05:24 AM

OK, I did a wrong copy of main.cf - now it's updated - that's the correct version.
Unfortunately the problem happens both when sending and receiving mail.

**joximu** · 03-15-2011 08:33 AM

sending:
try stopping the authdaemond - postfix should be able to handle the sasl things alone.

reading:
you have to have a look in the /var/log/mail.log - search for courier....

if webmail reading works then either imap is working or only localhost works... - but better have a look if you find more info in the log...

/J

Martini · 03-15-2011 10:54 PM

The problem still persists - I've stopped saslauthd and restarted postfix and all four courier daemons, but it still doesn't let me log in from my mail client. Webmail works perfectly fine.
The only thing I've found in mail.log about courier is this:

Code:

Mar 11 09:10:19 server amavis[1111]: Courier proto code   NOT loaded

If of any help in solving my case, I've followed the instructions from this address:
http://howtoforge.net/perfect-server-deb...onfig-2-p4
to set up my mail system with SMTP-AUTH and TLS.

**joximu** · 03-15-2011 11:04 PM

hm... normally it's enough to install a fresh debian (no package) and then add the packages needed by ispcp, then the configuration of all needed packages is done by the setup routine.

so - you don't need to setup a "perfect server"...

well...
I think there are severall things not s they should be... and you don't seem to have a deeper knowlegde of linux, or the internet protocols oder other practical things for ISPs...

hm - I'd ask someone to help you (directly on the system) or at least give someone the login data to a mail account so he can make some deeper tests...

I don't have the patience to guide you through all commands here in the forum sorry.

The only problem shown here is that you are accepting mails for local (non-virtual) recipients, and there's a conflict regarding the www-data user. See the following lines (they are cut so the full maildir folder where it's trying to save the mail isn't shown):

Code:

Mar 10 14:30:03 server postfix/local[22676]: B350E33C31E: to=<www-data@server.witchermod.org>, orig_to=<www-data>, relay=loc$

Mar 10 14:40:03 server postfix/local[23600]: warning: maildir access problem for UID/GID=33/33: create maildir file /var/www$

Basically, "www-data@server.witchermod.org" is detected as a local account because "server.witchermod.org" is your mail host name (mydomain in the main.cf) and "www-data" is an existing user in the machine. Then, it tries to deliver to the user's $HOME/Maildir maildir, that in this case maps to "/var/www/Maildir", a folder that cannot be created by the www-data user, and hence the error.

That said, solving this is as simple as changing the "mydomain" setup variable to "server.witchermod.org.local" and restarting postfix. Then add "server.witchermod.org" as a normal (sub)domain in ispcp and setup any mail accounts you want from there.

Regarding the authentication problems, there is nothing wrong shown in this log. Anyway, I suspect that you are hitting this problem regarding Outlook 2010 and the NTLM authentication failures (the solution is explained there).
