Hello,
I’ve setup email successfully and can send external emails via roundcube, but I’m having trouble sending any IMAP email. See the following error:
Server error: '554 5.7.1 <[email protected]>: Relay access denied'
I always get this back when sending emails and I can’t figure it out. Perhaps I missed a step when setting up the email initially, but I don’t believe so. Firewall info is below.
