DNS zone settings for Postfix & Exchange Online

KamilL

New Pleskian
Hello community,
I'm currently hosting three domains on my VPS. I got
- my main domain
- a domain with e-mail addresses hosted by postfix&courier
- a domain which is used for my MS exchange online plan

Later this days people told me that they get sometimes an error "451 Requested action aborted: local error in processing"' when sending emails to my exchange plan.
If I send e-mails from my own domain to my exchange plan everytime I get the error "550 5.1.1: Recipient address rejected: User unknown in virtual mailbox table"'.

// Edit: I solved the problem with disabling e-mail service on my exchange plan domain with "/usr/local/psa/bin/domain -u domain.com -mail_service false".
