Hi team,
I'm working on a personal mail server project and I'm hesitating to go with Roundcube for webmail. It seems to be the gold standard, but I'm afraid of getting bogged down in a nightmare installation. Honestly, guys, how stable is it? I'm looking for something solid that runs without me having to spend all night on it. I've seen links to support forums for netlinking and visibility, but I'm really interested in the pure technical side of things. Does anyone run this on a small configuration? Is it smooth, or does it slow down when there's a bit of traffic? I don't want to set up a complicated system just to read three messages.
I would consider Roundcube stable and easy to configure. It can get complex if your looking to add things like calendars, contact syncing, LDAP, Filters, etc. since all of those things are very environment specific.
I've run Roundcube on very small servers with any issues, as long as you run PHP it doesn't take up many resources.
