I am having issues with being able to send and receive emails. It was working and then is stop suddenly. I have emails that are stuck in a queue and I want to resend them. Looking at the logs the error messages read as followed:

Looks like a typo in the configuration. vitual instead of virtual.

Where would I go on the server to correct the misspelling? I am new to Postfix never used it before.

I don't know for sure, but according to the documentation, it's probably the line
in config file /etc/postfix/main.cf.

My server also has a line
To be certain, I would search all files under /etc/postfix for the string "vitual" and correct any occurrences.

Don't forget to restart Postfix afterwards.

So then how did you set it up to begin with?

Thank you bernbausch I made the change and my emails that was in queue are no longer there. How do I verify the email went to were they were supposed to go?

I suggest you create a new question. I know very little about Postfix (and only answered your question because the error was rather obvious to me).

I appreciate your honesty.

You should check the logs (usually /var/log/maillog or /var/log/mail.log).
