    Hi When email is sent using php email scripts from a website of domain.com.au (this one of domains web-hosted by a VPS (its domain is domain2.com.au))
    SOME remote mail server recognizes the sender as username@server1.domain2.com.au and does not accept the email.

    When an email was sent to username@domain3.com.au, full description of the result in Mail Delivery Reports in WHM is as below:
    SMTP error from remote mail server after RCPT TO:: host mx1.domain4.com.au [220.244.xx.xxx]: 553 5.1.8 ... Domain of sender address username@server1.domain3.com.au does not exist

    When an email was sent to username@domain5.com, full description of the result in Mail Delivery Reports in WHM is as below:
    SMTP error from remote mail server after MAIL FROM: SIZE=1986: host extmail.domain5.com [61.9.xx.xx]: 550 5.1.0 Sender rejected. IB506

    Please help how to solve this..~!

    The hostname of your VPS is server1.domain4.com.au, but there is no A record for that.

    Edit the DNS zone of domain4.com.au and add the A record:

    server1 14400 IN A 112.140.182.121

    In the DNS Zone for domain4.com.au, add an appropriate A-record that maps the server1.domain4.com.au hostname to an IP address.

    Ex:

    server1 14400 IN A ###.###.###.##

    or

    server1.domain4.com.au. 14400 IN A ###.###.###.###

    - where ###.###.###.### is the main IP address on server1.domain4.com.au

    This must be done on the authoritative nameserver(s) for domain4.com.au

    Once you get that done, for better email functionality you should have your IP provider add an appropriate rDNS (reverse DNS) record to associate ###.###.###.### with the hostname of server1.domain4.com.au. Right now the rDNS resolves to "unassigned." -- which you can see by doing an "nslookup ###.###.###.###".
