Sender verify failed

Highroller
Hello, i have a VPS where i host 4 different sites. Each site has its own deidcated IP adress (and ssl) and its own cpanel account. I have a problem with 550 sender verify failed, the error occours when i am sendeing mail from my wordpress site (sucuri plugin) and when i send mail to an gmail account. I notise that when i am adding my email account to clients like outokk it wont discover my mailserver as mail.receiver.no but mail.server.hostname.no. Here is the error message: This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
mail@receiver.no (ultimately generated from mail@sender.no) host receiver.no [91.229.xxx.xx] SMTP error from remote mail server after RCPT TO:: 550-Verification failed for 550-The mail server could not deliver mail to mail@server.hostname.no. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries. 550 Sender verify failed
So i own both of the domains (both sender and receiver) The receiver.no domain is hosted on a shared webhotell with its own mailserver, the sender.no domain is on my vps. Any tips to what i am doing wrong?

    Hello :) Could you post an example of one of these messages from your /var/log/exim_mainlog file so we can better understand the issue? EX:
    exigrep user@gmail /var/log/exim_mainlog
    Thank you.

    Please remove any real details (email address etc) from output like that and wrap it in code tags.

    Hello :) I suggest enabling SMTP authentication in the script you are sending email from so that it sends from a authenticated email account instead of from "user@$hostname". Otherwise, the remote mail server may reject messages coming directly from the server's hostname. Thank you.

    Thank you for your reply. I forgot to mention that the plugin (sucuri security) is sending emails to a mail account on my domain, and i have set up mail forwarding from that account to the account named mail@receiver.no i my log. So the error occours when the mail i is forwarded.

    Right, it's still an issue because the original mail is coming from user@hostname per the bounced message. Is it possible to use SMTP authentication in your script? Thank you.
