complete and extensive email solution

Hello Due to recurrent email severe problems using Kmail (, i am searching for an other email client solution, in STABLE release. I was interessed by kmail complete solutions for PIM, email, calendar and RSS readings. but are there some other solutions that could cover so much of these needs. I have experience in using evolution, which seems interesting, but are there some other programs ? I would be overall interested in the possibility to send some emails at certain schedules ; for example, to write mails during WE and those to be automatically sent on monday morning, for example. for other characteristics I am searching for : complete email solution, with html and multiple mailboxes, rss reader, calendar, PIM and so on. the possibility to synchronize calendar with my mobile phone through bluetooth would be nice but it is not indispensable. Maybe such solutions exist in java programs ? Note : I do not want to hear about thunderbird. thanks for your help

If you do not like TB then have a look at evolution (runs fine on KDE).

PC: oS 11.4 (dual boot 12.1) 64 bit | Intel Core i7-2600@3.40GHz | KDE
4.6.0 | GeForce GT 420 | 16GB Ram
Eee PC 1201n: oS 11.4 64 bit | Intel Atom 330@1.60GHz | KDE 4.7.4 |
nVidia ION | 3GB Ram

Yes, Evolution seems to be extremely complete and versatile, although, before i do anything, i would like to know if there is something else available like this …???

Like many here, I have decided to move away from kmail/kmail2, which was a real concern after using it since the medieval times. I do not like too much TB but at the same time wanted a software that could be found on all platforms and would not betray me again like kmail. So I chose SeaMonkey that I have now been using almost 2 months. It was extremely easy to set up, but I had to recreate manually my address book, which was less painful than feared. May be not the perfect mail client, but fast and stable, and does the job for me. Maintained as a fork of TB + Mozilla, I think we can trust its future.
