I've foolishly started to build my own, which at some point may become good enough to open source (I certainly don't want to commercialize it).
Looks like pretty straightforward PHP4. I wouldn't really hold that against it unless you plan to do development with it.
> it's also written in PHP... which doesn't necessarily have to count against it, but makes me a little wary
Sending and receiving (duh)
delayed mail (in case I make a mistake... And I will!)
filtering (and tags/folders)
simple search, with folder/tag support
browser-based, so I can access it anywhere
(Although I usually kill the default tags that Thunderbird still includes as a hangover from the original Thunderbird release because that way I get useful tag names in the Maildir should I ever need to hack on them directly.)
Oh man. As a longtime Thunderbird user, I have to say, that's a loaded question. :)
Sadly, a full on "here's a hierarchy of tags, just display mail by tag" mail reader doesn't exist to my knowledge outside of GMail itself :(
I use Thunderbird with a cheap fastmail.fm account. You can access your fastmail account from anywhere with their web interface. You can access it from any imap client.
It all works good enough for me. Not fantastic, but good enough.
I love nearly everything about Pine, but I wish that Dovecot's IMAP searching was faster.
But none really compare too favorably with Gmail. Zimbra was looking good before it went to yahoo and then VMware.
Can you elaborate?
The problem with Zimbra is that it tries to mimick Outolook on the web, not to be actual webmail.
If you like Outlook, you'll feel at home, but compared with Gmail it just feels to old school.
And it is slow, even inside a LAN.
problem with most webmail apps seems that they want to be desktop apps for some reason and completely miss the point imho
One is how nice it is to have ubiquitous web-mail, integration with my Android, etc. Some of these problems I think I can solve with my own brain-sweat, and obviously this thread might help.
But the other is spam. Before gmail, I hated spam. After switching to gmail (I guess about 5 years ago), I gradually lost my memory of spam ; I get less than one piece of spam per month. Is spam gone these days? Are there good open-source low-maintenance solutions?
It's very much hitting the basic, fast spot though, rather than the gmail style.
If you are taking about using something like Sup then I think there is too much faff should you ever decide to migrate away from it. Whilst it looks and works great it is useless for interoperability with your phone etc..
It was forked though as Bongo: http://bongo-project.org/Main_Page
We did fork the code and have moved on quite a bit we are in dire need of front end developers to help make a great frontend for a fantastic backend system. if anyone is interested in helping out please come by the IRC channel or the mail list
For those that are interested the IRC channel is #bongo on irc.oftc.net
We have some bindings to allow for webui development we have a complete PHP one which we used to plug roundcube's interface onto our backend. The others are in different stages of completion, there is the start of a mono binding and a ruby one so any help with these parts would be greatly appreciated.
I don't use web interface too much though.
I don't see the web interface too often anyway.
Universities often use Squirrelmail. The most recent instance I saw was for Potsdam.
Now that Firefox mobile is getting good too, maybe Thunderbird mobile will start to happen in 2012?
(I know technically with most FLOSS licences you don't need to share the code unless you distribute it, but it would completely miss the point to call it open source and not distribute the code)
The OP is looking for a webmail, open source solution similar to Gmail.
