I have a problem with the new version of mailinabox.
I am using mailinabox for more than 2 years. for a new domain, I have installed the latest version of MIAB. in this version I cannot send emails from client software using pop3 or IMAP.
It means if I login at box.example.com/mail everything is ok. but in client software like windows 10 mail app I can only receive the mails and sending is impossible.
I have check firewall and open ports and configurations. everything seems fine.
no software works.
Does anyone test the latest version of MIAB? It seems like a bug in the last version.
Thanks for your support.
