I just upgrade the stable version to 6.0.0-Alpha and I found the Email sending function no longer works.
I tested both office 365 and Gmail.
Error message for office 365
Failed to send mail (sender=xx , receiver=xx,)
Error [120]: Ran into problems sending Mail. Response: 501 5.5.4 Invalid domain name Error [126]: ‘tls://smtp.office365.com’ does not support authenticated connections.
Error message for Gmail
Failed to send mail (sender=xx , receiver=xx,)
Error [120]: Ran into problems sending Mail. Response: 501 5.5.4 https://support.google.com/mail/?p=helo r8sm18904374pfk.80 - gsmtp Error [126]: ‘tls://smtp.gmail.com’ does not support authenticated connections.
I noticed that the new email function use " name <name@mail.com>" as the sender but not the “name@mail.com” before. This maybe the problem of sending email.
I also find that in mail sending function for proposal, order and invoice, the “to” or “cc” can only be chosen from pre-defined emails of supplier or customer. However, we need to cc our company staffs as well.
