I tried to install roundcubemail on a testserver which is used only for zabbix atm. I realized that the mailserver is installed as a dependency. My intention is to use the existing imap server I installed on another nethserver and not one locally installed on the testbox.
Is that possible and if so where to modify the imap and smtp settings of roundcubemail? And can I somehow change the dependencies on this roundcube mail application as I have no need for an additional mailserver locally installed on the testbox?
Furthermore I would like to use an external smtp server on this roundcube mail for sending mails.
I certainly could install webmail on the prod (mail-) nethserver, but then again I want to use a newer roundcubemail version which is not available in official nethserver repo. Thats why I tried the above in the first place so I can tinker on a testbox and ex. install community version of newer roundcubemail without touching the production mailserver.
I would really love to see an updated roundcubemail version in the main repo anyway, mostly because of the elastic theme supported by roundcube >1.4
Thanks in advance for your comments and maybe hints.
I started this as the nextcloud mailclient is not satisfying our needs although it can exactly being configured with local imap but external smtp server. But way to often it is unavailable because of a nextcloud update till the app is separately re-activated after an update.
Thus I also thought I should maybe test rainloop mail app within nextcloud, but there I also would need to know if it is possible to configure an other smtp server domain then the imap domain.
