We use neth as imap server, while sending mails through externally hosted smtp server. As it was easy to configure internal neth imap but separate smtp server in nextcloud mailapp, we started using that thing, but I realize that it is to slow. It takes ages to refresh folders.
However, I’d like to ask which our alternative webmail options could be with this kind of setup, where a separate and external smtp server can be configured while imap from nethserver is used? A quick test with rainloop webmail app in nextcloud some time ago was not successful. Now I am thinking about trying roundcubemail or webtop as replacement. Is that possible with them and where/how would a separate smtp server be configured?
This reminds me a post where saitobenkei suggested some modifications that would allow us to configure internal smtp server which then would send emails through our external smtp provider with the user credentials. Maybe I should try this, but I will have to test this on a free weekend so I won’t screw our prod nethserver and could easily revert back through a snapshot if something goes south.
I still think that being able to configure smarthost for each individual user instead of one generic user only would be a nice feature enhancement for nethserver smarthost. The individual credentials could be taken from the users connector configuration
