    Today my Mailserver stopped working without any recognizable reason.

    It's a Server running Debian Jessie, which was set up following the perfect Server Guide for ISPCONFIG with NGINX. Few month ago I changed to the git source because of the support of hhvm support.

    When I try to send a E-Mail to a mailbox on the server this E-Mail get's rejected.

    I hope someone knows what is the problem here. Thank you in advance! :)

    This is producing the following logs:

    Check the dovecot-service in postfix (master.cf).
    postconf -M dovecot should return
    Code:
    dovecot  unix  -  n  n  -  -  pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/dovecot-lda -f ${sender} -d ${user}@${nexthop}

    Hi Florian,

    this returned

    Code:
    dovecot    unix  -       n       n       -       -       pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop}
    
    I changed deliver to dovecot-lda, now everything works fine. Thank you a lot!

    Through I am not sure what caused that problem.
