i just started to install and use roundcube. it works fine but i just want to use it on my gmail. i used yuno host guide but there was a problem.
i tried to add my domain in that way: gmail - settings - accounts and import - add another email address.
Gmail do not support port 993 for imap, and there is no STARTTLS encryption for smpt. firstly, tried to log in like that: smtp server: smtp.domain.tld, username: username, password: password, connection with TLS. eventhough i tried all of the log in combinations, i always got the error “DNS Error: DNS type ‘aaaa’ lookup of smtp.domain.tld responded with code NXDOMAIN DNS type ‘a’ lookup of smtp.domain.tld responded with code NXDOMAIN, code: 553”.
so what is the problem here?
