    Hi Users,
    I am using ispconfig since last 5-6 months for hosting couple of websites.
    Lets say example1.com & exampled2.com both hosted on same cloud server.
    I moved example2.com to IIS on my home server, I deleted example1.com domain, DNS, mailboxes from ispconfig panel.
    Now i am trying to send mail from example1.com to exmapled2.com.
    it shows below error

    SMTP Error (550): Failed to add recipient "user1@example1" (5.1.1 <user2@example2>: Recipient address rejected: User unknown in virtual mailbox table).


    I have commented below line in main.cf
    #smtpd_reject_unlisted_sender = no
    Still I am not able to send mails.

    I assume you mean example2.com here; did you delete the mail domain?

    My first guess is that you didn't delete the mail domain, as it's not in the list of things you deleted. That's why I asked:

    yes, I did from ispconfig web admin panel. I deleted domain, DNS & its associated mailboxes also.
    i think some of its files are still in mail cache.

    To be clear, when you say you deleted the domain, you mean from Email > Domain, not Client > Domains?

    What do you see from
    Code:
    postmap -q example2.com mysql:/etc/postfix/mysql-virtual_domains.cf

    out put if that command is domain name which i deleted.
    Code:
    user@server:~$ sudo postmap -q example2.com mysql:/etc/postfix/mysql-virtual_domains.cf
    example2.com

    Then it didn't get deleted. Does it still site up in the ui?

    If you go in the admin panel to "Email". Then the domain is neither listed in "Domains", nor in "Domain Alias"?
    If so, then you can go to "Tools" -> "Resync" and choose "Maildomains" -> "Start". After the changes are done, execute the command from #6 again

    domain is not listed in Domains & Domain Alias.
    I did Resync but still after performing command I get the domain name in output.:oops:

    You have a single server, not a multi-server installation?

    What is in your /etc/postfix/mysql-virtual_domains.cf? (don't include the password)

    What do you get from "grep -E 'db_|dbmaster_' /usr/local/ispconfig/server/lib/config.inc.php" ? (again, don't post the passwords, but do they match the other?)
