Talk:Virtual user mail system
Dovecot configuration suggests setting the certs 0444 for the .crt and 0400 for the .key, but the wiki suggests 0644 and 0600, respectively. Personally, I do not see why anyone should have write permissions on the certs, esp. since they're not meant to be modified. Suggestions? --Gesh (talk) 23:30, 9 August 2012 (UTC)
Also, shouldn't the chown nobody:nobody also be executed on the .crt file? I cannot understand the rationale of having it owned by root. At least with system-configuration files, you'd want both that root will be able to edit them and that *only* root be able to edit them. --Gesh (talk) 01:35, 10 August 2012 (UTC)
Problem with dovecot and roundcube
Hey there! Excellent tutorial, it almost worked like a charm! I had some problems with dovecot and roundcube. I'm not sure if they are sufficiently general to be added on the main tutorial, but I wanted to discuss them here:
- Dovecot Greeting. I had to place a Dovecot greeting in /etc/dovecot/dovecot.conf. I included "login_greeting = Dovecot ready for action."
- Instead of using TLS for IMAP in Roundcube I had to configure SSL. In particular, I had to change this "$rcmail_config['default_host'] = 'ssl://localhost/';" on Roundcube main.inc.php.
- I missed a comment on the 'username_domain' option in the configuration. As it was not mentioned in the tutorial I wrongly assumed that Dovecot allows login with only the username. But then I couldn't login from Roundcube using my username. Adding the "$rcmail_config['username_domain'] = 'mydomain.net';" option in Roundcube main.inc.php.
Hi! I cannot for the life of me get roundcube to work. It fails when I try to do the login to the IMAP server during installation. I get: "Connecting to tls://localhost/... IMAP connect: NOT OK(Login failed for [edited] from [edited]. Empty startup greeting (localhost:993))" I've tried changing it to ssl:// and without ssl:// or tls:// but for some reason it just does not work and I do not know where to go from here. Help would be greatly greatly appreciated. --Pei (talk) 04:20, 2 November 2012 (UTC)
Undid the last contribution of (Mehtab) because listening interfaces should beimplementation speciffic for this Postfix installation. If anybody disagrees let me know. Justforgetme (talk) 06:41, 4 December 2012 (UTC)
Expanded the Roundcube section and added some info for SpamAssassin and added the tip to remove "Received header". Had to do a bit of digging today to set it up, figured I add it here so it will be helpful. KingX (talk) 02:55, 21 April 2013 (UTC)
Thank you!, the best tutorial I found, just want to point out some problems I had during the installation.
A) If vmail id/gid != 5000, you may have dovecot-sql.conf correct, but postfix still complains for db access. Better listen to Svenstaro from the begining.
B) Roundcube installer: DO NOT TRUST IT!.
$rcmail_config['default_host'] = 'ssl://localhost';
If you use tls for IMAP, it will not work and you will get nightmares with the "STARTTLS command first" error. (roundcube tries to use ssl anyway)
You can use tls for the SMTP server thoug, but also keep the next lines like this:
$rcmail_config['smtp_server'] = 'tls://localhost'; $rcmail_config['smtp_port'] = 587; $rcmail_config['smtp_user'] = '%u'; $rcmail_config['smtp_pass'] = '%p';
If you use ssl, you also have to allow ssl connections. Change 'encrypt' for 'may' in your master.cf file, or you will have those nightmares again:
C) mysql.so and imap.so must be enabled (/etc/php/php.ini)
D) php.conf: You can create aliases for roundcube and postfixAdmin folders, so you don't bulk your /srv/http/ directory
E) Your hostname have to include your domain name:
lupus@ulula:~$ hostname myHostName.mysite.org
F) Bloking port 25 is a common practice for ISP's. This port is where all incoming mail is delivered, so you will not be able get your mail from the outside world. Don't panic (I did), you need a MX DNS server with port fordwarding (or convice your isp that blocking the smtp port is for loosers). This site offers the service for free, good enough to play around: 
Edit your master.cf file to something like this
smtp inet n - n - - smtpd 26 inet n - n - - smtpd submission inet n - n - - smtpd
Server refuses connection
Hello! Whenever I try to login to the mailaccount I created using postfixadmin with roundcube, I get the following error message (from roundcube):
IMAP Error: Login failed for firstname.lastname@example.org from my.ip.adre.ss. Could not connect to ssl://localhost:993: Connection refused in /usr/share/webapps/roundcubemail/program/lib/Roundcube/rcube_imap.php on line 184 (POST /roundcubemail/?_task=login&_action=login)
Also, when I tried to send an email to my account from another E-Mail adress, I got the following error report:
The recipient server did not accept our requests to connect. Learn more at http://support.google.com/mail/bin/answer.py?answer=7720 [(0) my.domain.com. [188.8.131.52]:25: Connection refused]
