I did notice that a hosting provider uses a single FQDN for multiple hosting servers running IMAP and SMTP. In my mail client I can configure mail.domain.ext as the IMAP and SMTP servers, and use my email address and password to authenticate via ports 993 (IMAP) and 587/465 (SMTPS). The email address and the password are stored on one of the hosting servers which has a different FQDN (eg sv1033.somedomain.ext). I would like to know how this is called and how this works. Edit: I did find this: https://doc.dovecot.org/configuration_manual/forwarding_parameters/ But still need to wrap my head around this matter as it looks to be rather complex. Does anyone have any suggestions? Thanks.
Do you want to distribute traffic for one FQDN over several servers? Then you'll need a load balancer. If you want a certificate that's valid for your FQDN's, see https://forum.howtoforge.com/thread...d-lets-encrypt-ssl-certificate-certbot.86372/
