I'm looking for a front-end/GUI to Postfix's
postconf, which makes it easier to investigate/adjust settings in
master.cf. Main goal is to get a better overview over settings already made ("active"), additional settings ("not yet active"), their relations, etc. – best with things grouped into categories (e.g. SSL/TLS settings, relaying, …).
Simple and easy-to-use solutions are preferred, focus definitely is to see connections, review settings, and have links/explanations for the used/available keywords and how to combine them best (or avoid conflicts). If your favorite goes beyond, it would at least be interesting to know about its existence – plus, if there's lack of "simple alternatives", it might turn out as the one I've got to use then. Similarly for the license part: FOSS is strongly preferred – but if not available, other solutions might be acceptable. But as I don't make money with the mail server (I rather have to put money to keep it running, ouch), I won't pay more than a "nominal fee" (say, USD 5) – almost nobody pays/donates me for all the services I offer (so I have to subsidize already there), which definitely lowered my willingness to do so.
- must be usable on Linux (web-app is fine)
- must not apply any changes without me explicitly telling it to
- must (obviously) work with Postfix
- must show settings (active ones and unused/not-set ones) in an organized manner (categorized)
- can auto-detect Postfix version and shows available/deprecated/recommended settings accordingly
- allows to make changes. If so, it should allow to "review" them first – or at least create backups of the altered files
- cares for "plugins" like Amavis (w/ SpamAssassin, ClamAV, etc)
- cares for Dovecot (which a.o. serves as auth backend via SASL here)
Not needed (but doesn't hurt as long as it doesn't interfere)
- user management. I already use PostfixAdmin for that – which unfortunately lacks the features to care about the other settings
Update: It shouldn't add to many other features. Certainly Webmin (see below) has modules to deal with Postfix. But the ratio of what_I_use:what_not is rather 1:50 with that. I'd prefer a "dedicated tool" here, especially as the machine is "small sized" ;)
