    Seit wan haben sie server in Deutschland?

    Wurde in der Tat erst vor Kurzem freigegeben. OVH hat VC an die Seite bekommen und sie expandieren derzeit global mit großem Tempo. Bieten auch innovative Cloudprodukte, aber mir sind dedicated Server derzeit noch am liebsten. Vor kurzem gab es einen OVH Summit in Paris. Gut, den Charme einer Google-IO oder von Apple haben sie nicht drauf. Dafür aber ein starkes Commitment zu Opensource! Vor allem, nachdem jetzt der Privacy Shield zerbrochen ist (falls der Link geht: https://plus.google.com/u/0/+AndreasSutor/posts/bQcLgoeK4wf ), brauchen wir europäische Lösungen.

    I'm referring to post https://i-mscp.net/index.php/Thread/13074-SRS-Plugin/
    But this case seems a bit different. In addition to the SRS subject I'm currently watching a special issue in the case of mail forwarding.


    Setup is as following:


    • 2 virtual servers, each with its own IP and some domains as clients.
    • Identical configurations on every machine.
    • OS: Debian Jessie, updated
    • i-MSCP: latest stable 1.4.7, any configuration left to defaults
    • MTA_SERVER => 'postfix',
    • PO_SERVER => 'dovecot',
    • SPF Plugin 1.2.0


    Few imap accounts, some mail forwarders as well as catchall are set on some domains.


    Following is the process that happens.


    1. One domain's Wordpress sends an information to the admin
    [email protected] -> [email protected]
    i. e. from VM1 to VM2
    result of mailtransfer OK so far


    2. Recepient server SSS.info has set a forward on wpadmin02
    Tries to proceed forwarding
    "[email protected]" -> [email protected]
    i. e. from VM2 back to VM1
    Where only by chance DDD.net is located again on VM1
    Rejected.


    Part of mail message is:


    Code
    1. This is the mail system at host VM2.DDD.net.I'm sorry to have to inform you that your message could notbe delivered to one or more recipients. It's attached below.For further assistance, please send mail to postmaster.If you do so, please include this problem report. You candelete your own text from the attached returned message. The mail system<[email protected]> (expanded from <[email protected]>): host VM1.DDD.net[IP VM1] said: 550 5.7.1 <[email protected]>: Recipient address rejected: Please see http://www.openspf.net/Why?s=mfrom;id=webmaster%40BBB.org;ip=IP VM2;r=VM1.DDD.net (in reply to RCPT TO command)


    3. Whole Message is submitted to [email protected] as bounced mail
    This is, what I received.


    Analyzing:


    Now the curious fact, wether related to SRS or not and in difference to bounced mails by providers like gmx.net or web.de:


    SPF txt entries in any mentioned domain is as follows


    "v=spf1 ip4:[IP adress or net range of VM1] ip4:[IP adress or net range of VM2] +a +mx ~all"


    That means, any domain is allowed to send from each VM.
    The correct configuration is confirmed by SPF website. :exclamation:



    Code
    1. DDD.net rejected a message that claimed an envelope sender address of [email protected]
    2. VM1.DDD.net received a message from VM2.DDD.net (IP...) that claimed an envelope sender address of [email protected]
    3. The domain BBB.org has authorized VM2.DDD.net (IP...) to send mail on its behalf, so the message should have been accepted. It is impossible for us to say why it was rejected.


    Current possible solutions:
    :idea:

    • I could create imap accounts for some purposes. Here: for WP Admin contact.
    • Trying to avoid forwarding generally, as concerning the SRS problems, this is a growing reason for bounced mails as SPF gets more implemented
    • One may think, that the reason is not related to forwarding in general but in forwarding as result of a catchall. I'm forwarding several catchalls to one general catchall address, which works fine so far. May be I have to recreate catchall adresses for each domain seperately again.

    This post is intended foremost as a report and I myself will keep an eye on that. Looking for other solutions. :?: As far as today I dindn't found some.

    Years ago I used a control panel at Strato in Germany (Vista24, proprietary and now dead). They had a special feature in mail forwarding.


    With i-MSCP you can have
    - an e-mail box
    - an e-mail forwarder to one or more addresses, even cascade them :-)
    - a catchall address


    In the mentioned program there was additionally
    - a forwarder for a multiple of addresses


    Example:


    I have subscribed to many newsletters, each with its own mailadress, say


    letter01@mydomain.tld pour Figaro
    letter02@mydomain.tld pour Le Monde
    letter03@mydomain.tld pour Financial Times


    itgeek01@mydomain.tld pour Framasoft
    itgeek02@mydomain.tld pour Opensaar e.V.
    itgeek03@mydomain.tld pour i-MSCP News


    Formerly I had forwarders like


    letter* -> [email protected] (being an imap-account, called separately from other mails)
    itgeek* -> [email protected]


    I tested with i-MSCP and wildcards were accepted, but not working as such but literally ;-)


    So my question is: could this be implemented without much work? Just by giving postoffice programs a regular expression?


    If this would not be possible I'm happy I read of another solution in this forum. There s. o. suggested to create appropriate subdomains, e. g. in this case letter.mydomain.tld and itgeek.mydomain.tld.


    Beyond comfort there is another reason for my question/suggestion. Today it happens more often, that mail addresses get lost because they get on spam lists. While still receiving valid mails amidst spam you can put them out of your everyday box when naming of the addresses is somehow structured (name-YY-MM). In praxis it happens like this: on a webpage I discover an interesting new newsletter. Without need for creating a new address for that I can order this letter by using the next number (letter04@mydomain.tld in the example above). This address is already covered by my "catchmultiple"-forwarder. The frontend needn't be changed with such a solution.


    What do you think?

    OK, thank you, haven't found this on search.


    Generally speaking:
    Are such things more subject for the forum or for youtrack?
    I want to add some more minor things I discovered while installing/using i-MSCP.


    In tab versions of the plugins, you mention "Version compatible with i-MSCP 1.3.x Serie".
    To me so far


    AdminerSQL, Mailgraph, Monitorix, OpenDKIM, PolicydSPF, RoundcubePlugins


    seem being compatible to 1.4.x Serie.


    Appreciating what you do and Thanks for your work!

    Hi,


    hopefully I'm not trolling with this post. ;) I'm referring to the closed topic
    https://i-mscp.net/index.php/T…ssin-Unerwarteter-Fehler/
    of
    team-o and Tappi


    Of the mentioned plugins, the one of PolicydSPF is red and missing in the wiki.
    As well are PolicydWeight and Postgrey.


    But you can find the same and relevant information for PolicydSPF at github:
    https://github.com/i-MSCP/plug…ator/PolicydSPF/README.md
    Perhaps s. o. pastes this into the wiki?

    Installation brought an error with some text as:
    "Could not install ... file ... to /var/www/imscp/gui/plugins/Mailgraph/tmp_graph/mailgraph...png"


    Solution:
    Added directory manually, changed owner and group.
    Restarted (forced) Installation.
    Installation completed.
    Found 13 files inside tmp_graph directory afterwards. Have to wait, 'till the graphs are populated ;-).
