New mail receive from Gmail using IMAP are not marked as 'new' by Claws Mail. They are instate mark as 'unread'. This causes some problems, for example notification plugin will not notify you of new email (because none of the arriving mail is seen as 'new' by Claws). I didn't have this problem using POP3.
Gmail problem.
Well. Saying that this problem is gmail problem is a bit simplifying. Thunderbird handle this ("new" markers on IMAP / gmail) correctly, so it definitely seems doable and may be it is not a gmail problem but Claws problem. And even if not, would it be a good idea to loose users because of half-way support for most used e-mail provider in the world? I tried to use Claws mail instead of Thunderbird for gmail+IMAP. And I must say Claws is simply great and this bug is the only one I cannot solve on my own somehow. So I reverted back to using Thunderbird for now due to this problem. I would like to see this bug reopen.
It's not simplifiying, it's a Gmail unsupported feature: http://www.google.es/support/forum/p/gmail/thread?tid=440a32502125d162&hl=en Please use the suggest feature link and suggest it so they can fix/enhance their IMAP implementation.
Ok, but Thunderbird somehow does it well. Maybe it has workarounded this specially for Gmail... but can't do Claws the same workaround?
Whatever tbird does, it's not really adequate. The point of IMAP is message flags like unread, tagged, etc, are saved server-side, so each client that you may use to connect to the imap server at any particular time displays the same information. This can't be the case with such a workaround.
That might be the point of IMAP, but the point of mail clients is to make what the server sends more usable. Take spam reporting. Claws has a few plugins that help cover the inadequacies of server-side spam alerting. Those plugins won't help if you view your email from a different client but they sure make it easier to keep using Claws. The same would apply here. Could we set up some sort of bounty to make it worth your time to add this feature, possibly as a plugin? As far as google is concerned they have no reason to support the Recent flag. They want us to use their web interface so they can show ads. There's a lot more hope in changing the claws developers' minds than googles.
Easier solution would be not using gmail. Hint: gmx.com
That's not a very productive approach though.
Indeed, I could fix gmail bugs in my free time I haven't thought of it.
Salvatore, it would be ideal not to have to use gmail. This lacking feature of theirs is only one of many. The problem arises in environments where the user doesn't really have a choice in mail servers (on the job for instance). That's where I myself am stuck.
This is an invalid and closed bug, please, move discussions into the mailing list.
