Do you use Courier or Dovecot? Did you set up any whitelist or blacklist records in ISPConfig?

 

Courier
Just checked ISPConfig - no whitelist or blacklist

 

Are you having problems fetching mails from the server?

 

I have the same account setup on multiple computers. On 1 of the computers I cannot send via my email address but I can receive. On the other 2 I can send and receive with no issues.

The reason I found this issue is because I am trying to find out why I cannot send. I have double checked all of my account settings and they match to the other computers.

 

Your IMAP daemon has nothing to do with sending emails. Are there any Postfix errors in your mail log?

Code:

iptables -L

?

Looks ok. Are you sure you are connecting to the correct mail server with your email client?

 

I have recreated this account multiple times and it still does not work.

I get the error every time i try to send email in my mail log:
imapd: Error reading ACLs for : Invalid argument when sending email
