[quote](other than webmail2)
Including webmail2 in my opinion. The integration is very poor and even if performance was acceptable I would not be able to offer the JF to my clients simply because the usability, compatibility and security are all so bad.
Usability: e.g. the quarantine message list is an utter mess. When I tested it recently I found wrong From addresses, wrong times (apparently converted to some unspecified server timezone), subjects cut short, subjects undecoded and no way to read a message before moving to Inbox.
Compatibility: very sad to see JF incompatible with other DH features like catch-all addresses, existing webmail.domain access, forwarding etc. esp. since this is a big fall-back from the previous spam defence it has now replaced.
Security: quarantine excluded from the data backup! And purge quarantined messages after 30 days, regardless of where business processes requiring and storage availability affording longer.
Overall the JF is a disappointing blot on the DH landscape. It is very sad DH had to release something so unfinished into production.
