A clients Accounting program emails remittance advices and generates this error with 7.0 pre1 - it was previously OK with 6.0.
Any way I can do a quick fix? - I cannot change the accounting system settings.
The accounting software is broken. Date headers have always been mandatory for SMTP email.
As a workaround, log in as root, then do:
mkdir -p /etc/e-smith/templates-custom/var/service/qpsmtpd/config/plugins/
cd /etc/e-smith/templates-custom/var/service/qpsmtpd/config/plugins/
touch 17check_basicheaders
