Zertifikate für E-Mail

Question

Guten Morgen liebe Community,

ich hab schon gesucht hier, aber nicht wirklich was passendes gefunden, darum mach ich jetzt hier nochmal nen Thread auf. Ich nutz Froxlor nun erfolgreich seit über einem Jahr auf zwei Servern, es funktioniert soweit auch alles mit LetsEncrypt und den Zertifikaten.

Jetzt hab ich nur folgendes Problem, bzw. ist dies möglich, da ich mehrere Kunden über Froxlor auf zwei Servern verwalte, muss ich natürlich auch E-Mails verwalten, und zwar verschlüsselt. Kann man das über Froxlor machen? Sprich, dass die Kunden ihre Emails über

imap.kunde1.de & smtp.kunde1.de sowie imap.kunde2.de & smtp.kunde2.de usw. abrufen können. 

Momentan muss man ja bzw. so hat es mein Admin gemacht, ein Zertifikat für alle hinterlegen, welches auch nicht automatisch per Script geupdatet wird?! -> Ist das so richtig?

Oder müssen alle Kunden ihre E-Mails per imap.hauptdomain.de abrufen?

ja, du kannst ja auch in der mailserver cnfig nur einen hostnamen konfigurieren; E-Mail clients sollten also als imap/smtp server das eintragen, was da ei dir drinsteht

Den Dovecot könnte man zumindest so einrichten dass jeder imap Zugriff sein eigenes Zertifikat hat  

Quote

/etc/dovecot/conf.d/10-ssl.conf

local_name imap.domain.de {
  ssl_cert = < /etc/letsencrypt/live/imap.domain.de/cert.pem
  ssl_key = < /etc/letsencrypt/live/imap.domain.de/privkey.pem
  ssl_ca = < /etc/letsencrypt/live/imap.domain.de/chain.pem
}

local_name imap.domain2.de {
  ssl_cert = < /etc/letsencrypt/live/imap.domain2.de/cert.pem
  ssl_key = < /etc/letsencrypt/live/imap.domain2.de/privkey.pem
  ssl_ca = < /etc/letsencrypt/live/imap.domain2.de/chain.pem
}

Du kannst die configs nach Belieben anpassen dafür sind sie da. Und sie funktionieren wunderbar out-of-the-box. Bei unseren Vorgaben geht es hauptsächlich um die Anbindung der Konten aus der Datenbank - ssl ist Admin Sache. Und da froxlor Open source und frei von jedem auf der ganzen Welt nutzbar ist gilt nicjt für alle die dsgvo

      Dear Froxlor Community,
      I am proud to finally release the stable version of a new API based froxlor. Due to massive internal improvements and changes in the core (almost 600 commits since 0.9.40.1) users are now able to list/create/edit/delete resources and entities of froxlor via API (requires activation of api-usage in the settings and a user based API-key). The froxlor frontend itself uses the API backend too.
      Froxlor now uses composer to include some of its requirements like phpMailer, Logger, IdnaConvert and TwoFactorAuth libraries. All required files will be included in the official tarball so you do not need to worry about installing and using composer (only if you are using / testing the git-master, see https://github.com/Froxlor/Froxlor/wiki/Install-froxlor-from-git-sources).
      Most important changes:
      froxlor now requires at least php-7.0 or newer, php-5.6 is no longer supported because of its EOL almost a year ago you can access data via API, for more information see https://api.froxlor.org/doc/. An example can be found here: https://github.com/Froxlor/Froxlor/tree/master/doc/example PHPUnit tested API backend with MySQL 5.6, 5.7 and 8 as well as MariaDB 10.3 and 10.4, see https://travis-ci.com/Froxlor/Froxlor compatibility for MySQL8 2FA (two-factor-authentication) for admins/resellers/customers (email or authenticator app) all froxlor-database tables will automatically be converted to the InnoDB engine added support for Debian 10 (buster) and Ubuntu 18.04 (bionic beaver) implemented Let's Encrypt via acme.sh - Note: all your current Let's Encrypt certificates will be removed and re-created due to another structure customizable error/access log handling for webserver (format, level, pipe-to-script, etc.) deprecated Debian 7 (wheezy) and Ubuntu 14.04 (trusty tahr) support dropped support for Ubuntu 12.04 (precise pangolin) dropped ticketsystem Changes in 0.10.1:
      allow/disallow API access on a per-customer base add explicit tlsv1.3 ciphersuite setting fixed wrong behaviour in Ftps.add() if customer is newly created and setting customer.ftpatdomain is true added expiration date to SSL certificates loaded via API request fixed wrong return in Certificates.get() if given domain does not have a certificate allow setting http2 flag for (sub)domains in customer view, fixes #725 Changes in 0.10.2:
      force Let's Encrypt ACMEv2 API, fixed #728 added default-ssl-vhost settings and optionally allow including of non-ssl default-vhost settings, fixes #727 implemented DomainZones.listing() to return custom stored dns entries removed API Parameter use_default_ssl_ipandport_if_empty from Domains.add() added API Parameter dont_use_default_ssl_ipandport_if_empty to Domains.add() fix registration and termination date to flip between empty-value and 0000-00-00 Download: 0.10.2

      Note: Debian packages will be created and released as soon as possible, please be patient
      Attention: The auto-update feature is currently unavailable due to the archive taking a bit longer to extract and froxlor trying to redirect too soon thus leading to an internal server error. A quick reload does "fix" the problem but it's not very clean and therefore I removed the 0.10.0 release from the autoupdate server to avoid that. Please use the manual update options, see https://github.com/Froxlor/Froxlor/wiki

      Thank you,

      Hi everyone,
      I'm running a Debian 10 Buster Server with PHP7.3 installed. The PHP7.3 update is the new component in the system. since then, I can't find any Mailboxes. There are no folders in the var/customers/mail/[customer] directory.
      If you take look at the Screenshot, you see, that the E-Mail adress is existent in Froxlor.

      If I missed a log, please let me know, so I can attach it

      Hi,
      Wile doing migration of email accounts from one froxlor server to another I have noting some thing.   Expecting some clarification on this.  As we all know emails are normally stored in the location "/var/customers/mail/user/domain.com/user/Maildir/" .   I create email accounts via froxlor panel and copy the email files directly via scp or rsync from old server to new.  The strange thing I have noticed is it is not coping custom folders and its emails like we have in source.  
      The solution I have found for this is to use imapsync between old and new.  imapsync is preserving custom folders like as it is in source.    Does it mean custom folder settings are stored somewhere else?  How we can preserve it and copy emails manually?
