I don’t know what this means.

You need to look at the logs or the journal for the postfix unit. You haven’t told us your OS and version, so I can’t tell you specifically.

My OS vervision is ubuntu Linux 22.04.4

When i send with my domain after installing the virtualmin it shows me it successfully send but the recipient does not receive it in is email box

Logs (logs are king) on this would be handy, sounds like your provider is blocking port 25.

[kalimanti]

My vps port is opened

Please Joe help me out

outbound, alot of VPS provider’s block that port (due to spammers) and you need contact support to request it to be opened.
You need to show the logs when you send.
Another way to tell is mail getting queued, the queued messages should show the error.

[kalimanti]

It shows 16 mail queue

[stefan1959]

click in there, the 15 messages should show the error why they were not sent

Yep, looks like your provider is blocking your outbound port 25
