I have a client who uses Sage Line 50 2013 (about to upgrade to latest version), and they usually send invoices and statements directly through Sage (not the best email client in the world, but…).
I have been informed that some emails are successfully being sent, whereas others are not. Sage provides no information in that regards, it either returns a prompt saying “Failed to send email” without any further information (Nice), or a prompt that says “Emails sent”.
My question therefore is, which logs do I need to be looking at? I’ve had a quick nose at the /var/log/mail.log but that appears to be mostly babbling on about logins (successful and unsuccessful).
Many thanks in advance.
