How satisfied are you with RoundCube?

[IT_Architect]

I'm getting ready to set up 3 new boxes and 5 instances of DA (ESXi). Many of you have had standard Exim / Squirrel Mail e-mail like I have now. I'd like to hear about your experiences using Roundcube on a reasonably busy server with quite a few clients. I read about the recent exploit and how long it took to fix. Some questions I would have are:
1. How reliable has it been for you?
2. Do you still get SpamAssassin?
3. How do you do AntiVirus? Can I still use CLAMAV?
4. Any big performance hit that you've noticed?
5. Any problems with big attachments?
6. Any problems with HTML mail?
7. What other advantages are there? E.G. can you tell it to delete all e-mails older than X days old? Replication for fail-over?

Thanks tons!

Very reliable and customers love the 3 Pane Layout theme
It's a Web Mail client so yes it treats emails as any other MUA would, and has no effect on SpamAssassin, ClamAV or any other MTA's.
I send and receive emails with a max size of up to 50mb and occasionally have to go to RoundCube to pick them up. No problems what so ever.
Handles HTML emails very well, blocks images from unknown sources and gives the option to load any remote images when it does so. Very effecient.
You can select multiple emails from a folder (CTRL+A) and perform various tasks like empty folder and so on, sort by date the usual suspects.
Also I've expierence of using it with POP and IMAP and it was very well suited to both MTA's.
