Impossible to login to my mail server : webmin/virtualmin/postfix/dovecot

Good sleuthing, Julien.

I'll add to this (which is a great story of debugging POP) that the maillog (or wherever Dovecot is logging) would have given a quite informative error about the missing directive. It's always worth checking the mail log while doing any debugging of mail problems (likewise for Apache and the error_log, and BIND and wherever it is configured to send logs, usually /var/log/messages via syslog).

Im having the same problem.

I have seen this in the mail log.

fatal: /etc/postfix/master.cf: line 15: inet service cannot be private
I have changed all these settings to: inet n, there was 3 in master.cf.

then i got the error:

/var/spool/postfix/etc/resolv.conf and /etc/resolv.conf differ
Feb 16 15:32:19 li6-87 postfix/postfix-script: starting the Postfix mail system
Feb 16 15:32:19 li6-87 postfix/master[16902]: daemon started -- version 2.3.8, configuration /etc/postfix

but postfix did start.

then on the mail client in imap I get the error:
Plaintext authentication is disabled,

so i tried both settings:
disable_plaintext_auth = no
disable_plaintext_auth = yes (in dovecote)

still no change, also when trying to login with pop this error.
...cannot be contacted on port 110.

this all works>
telnet mydomain.com 110
Trying xxx.xxx.xxx.xxx...
Connected to mydomain.com
Escape character is '^]]'.
+OK Dovecot ready.
USER myname.mydomain
+OK
PASS 12345
+OK Logged in.

latest error in mail.log is this:
dovecot: imap-login: Aborted login:

Im new to Linux and virtualmin so could do with some help if anyone has any ideas.

OK i got imap working by changing the settings both in the dovecot.conf and on the server page, SSL Configuration, to both no.

POP still does not work and I cannot get any more details from the logs even with all turned on, but im not too bothered about that, main concerns are security, is it now safe?

with these settins

disable_plaintext_auth = no (this has to be no for imap to work)

in dovecot setting s
Disallow plaintext authentication in non-SSL mode? this has to be set to no for imap to work.

So Im going to start a new thread on this as its going off track but I used the GPL install script on fresh debain4 setup, no errors on set up, but I'm having some problems now with email. right now its spamassain

here is the gist:

=errors

this one seems continues I change it and it returns.

Virtualmin is configured to setup DNS zones, but this system is not setup to use itself as a DNS server. Either add 127.0.0.1 to the list of DNS servers, or turn off the BIND feature on the module config page.

constantly get this but in the Hostname and DNS Client, there are 3 boxes for DNS servers, each one has an ip 1) 64.62.190.9 2) 65.19.175.2 3) 65.19.176.2 every time i add 127.0.0.1 in and replace one of the others then go back to the Recheck Config selection it returns with the same error:

Virtualmin is configured to setup DNS zones, but this system is not setup to use itself as a DNS server. Either add 127.0.0.1 to the list of DNS servers, or turn off the BIND feature on the module config page.

on the SpamAssassin Mail Filter page this error:

in /etc/procmailrc. this is all there is:

i am basically stuck getting spam sorted and the first dns problem resolved.

please advise.

added this code in /etc/procmailrc then lost this error

SpamAssassin does not appear to be set up in the system's Procmail configuration file /etc/procmailrc, so any configuration done using this module will have no effect unless users have it set up individually.

SpamAssassin seems to be alive:

so inside /var/log/procmail.log i have a few blocked mails and this strange one:

bin/sh: //etc/webmin/virtual-server/lookup-domain.pl: No such file or directory

http://www.virtualmin.com/index.php?option=com_fireboard&Itemid=77&a...

But the full set of .pl files that should exist are :

/etc/webmin/virtual-server/clam-wrapper.pl

/etc/webmin/virtual-server/sendratings.pl
/etc/webmin/virtual-server/spamclear.pl
/etc/webmin/virtual-server/spamconfig.pl
/etc/webmin/virtual-server/writelogs.pl

BUT I have these missing files:

/usr/bin/locate lookup-domain.pl
/usr/bin/locate lookup-domain.pl
/usr/bin/locate procmail-logger.pl
/usr/bin/locate clam-wrapper.pl
/usr/bin/locate fcgiclear.pl

/etc/webmin/virtual-server/sendratings.pl
/usr/bin/locate /etc/webmin/virtual-server/spamclear.pl
/usr/bin/locate /etc/webmin/virtual-server/spamconfig.pl

so i added this file which I found a copy of on this site: lookup-domain.pl

#!/usr/bin/perl
open(CONF, "/etc/webmin/miniserv.conf");
while(<CONF>) {
$root = $1 if (/^root=(.*)/);
}
close(CONF);
$ENV{'WEBMIN_CONFIG'} = "/etc/webmin";
$ENV{'WEBMIN_VAR'} = "/var/webmin";
chdir("$root/virtual-server");
exec("$root/virtual-server/lookup-domain.pl", @ARGV) || die "Failed to run $root/virtual-server/lookup-dom$
~

I still need to find a copy of what should be inside:
procmail-logger.pl

cannot find that anywhere...
