Bug Description

On a slow connection, kmail+imap is almost impossible to use due to its slowness.
My connection is particularly slow in the outgoing direction (about 10kb/sec).

What I don't understand is that attachments are supposed to be downloaded on demand, but each time I check for mail, it takes for ever when some messages have big attachments. Opening the "task list" I see

1. downloading message data. This is reasonably fast
2. sending message data. This is very slow. It seems to me that all attachments of all new messages are sent back to the server !!

The second step always occur, even if I don't click on messages with attachments.
Due to this, it is really IMPOSSIBLE for me to use kmail.

I have to use thunderbird, which has no problem at all. Everything is fast and responsive with thunderbird (with the same IMAP server). Attachments are downloaded only when I click on the message, and they are not sent back to the server ! Dealing with messages with attachments is about 20x faster with thunderbird...

I'm very sad of this because I like kontact very much.

(forgot to say I have a brand new kubuntu hardy 8.04)

Thanks for reporting this issue and helping to make kubuntu better.

Yes, this is true and a known problem. However, kmail will not be further developed since it will b superseeded in KDE4 by Kmail2. Kmail2 will use also Akonadi for the imap connection. This is all totally new code, therefore this report would not apply to it.

Thanks again, and please do not hesitate to report issues in the future.
