    I don't know if any updates caused this but when i send emails to any of my domains on ISPconfig 3 I get an Undelivered Mail to Sender

    <[email protected]>: user unknown. Command output: ERR: authdaemon:
    s_connect() failed: Permission denied Invalid user specified.
    Reporting-MTA: dns;
    X-Postfix-Queue-ID: 133571224071
    X-Postfix-Sender: rfc822; [email protected]

    I know for sure that the user exists and I can send emails with it but even if I try replying then the email is not delivered.

    In mail.log there are no errors besides the bounce.

    Any ideas how to resolve this?

    Which distribution do you use? What tutorial (URL) did you use to set up the system?

    I used the Perfect Server ISPconfig 3 on Ubuntu 9.04. Everything was working smoothly unti the maildrop broken packages were upgraded.

    I followed the fix to downgrade to 2.0.4 and to hold maildrop from updating. That fixed the problem of not delivering mails to the mailboxes and after a couple of weeks this happened. (I don't know if any update caused this, since I 'm doing aptitude safe-upgrade every other day)

    Ok issue resolved. There was a line in postfix/ for maildrop that wasn't correct. sorry to bother you
