I’ve come to discover, that after upgrading from 8.3.0~667 to 8.4.0~728 that
- some e-mails show no sender at all as well as on WebApp and on mobile devices (iOS
- Some mails won’t open on WebApp (failed to open Dialog)
- and I can not use the reply-to feature in any mail (empty recipient when editting mail)
I have not changed any postfix configuration. The e-mail headers appear the same. I am running a mail server with postfix and then forwarding the mails via lmtp.
I ended up downgrading Kopano Core to the previous version.
I’d be glad to find some help.
