3 major issues.

1.Getting error when using SMTP to send out email.
*SMTP -> ERROR: DATA not accepted from server: 554 mail server
permanently rejected message (#5.3.0)*

2.Emails getting bounced back - non delivery every morning mostly
(attached email rejection receipt)

3.Emails getting lost from external domain

Please help us to resolve this ?

I'm wondering if the upgrade has completed correctly. What about switching to Postfix, then back to Qmail (procedure is described in KB)? Might that solve the problem?
