still working out the kinks of my Perfect Server CentOS 8 install Roundcube (or /webmail) isn't sending out emails. it reads them fine, just doesn't authenticate when sending. the /usr/share/roundcubemail/config/config.inc.php file is a copy/paste from the instructions. elsewhere, i've seen references to setting the user and password variables to default to spaces - that didn't work. and changing the SMTP from localhost to a tls://valid.server.name and port didn't work either. Thoughts on what I might be missing? thank you!
