Something changed in TW 2023020[123]+, KDE3:kmail3 can no longer send via SMTP details of the SMTP server Port with SSL: 465 or 587 Port with TLS: 587 Port without SSL/TLS: 25 Authentication method: Password Requires sign-in Yes And also TLS pop stopped working and I have to import in plain from port 110: Port with SSL/TLS: 995 Port without SSL/TLS: 110 Username: Your username Password: Your password Authentication Type: Password I think it was working OK yesterday, so 20230202 seems most likely. On another TW machine, last updated in 2022, the old version kmail3/TW can handle the same mail folder (using NFS to access the same mail folder remotely). The following was logged, seems to point to protocol issues, but /etc/crypto-policies/back-ends/opensslcnf.config is the same on both new and old TW systems. I tried disabling apparmour, but that didn't seem to help (but maybe I did that wrong - used yast-services and a reboot).
