I want to check my emails from gmail. I can’t use roundcube from all devices. Any solution?

You can’t use that because InfinityFree doesn’t offer SMTP and IMAP/POP

Yes, buy a GSuite account so you can have Gmail for your domain. Or try your luck with the email forwarders, but Gmail is notoriously bad with accepting forwarded emails.
