Dear Zhanghuangbin,

I performed migrating from 0.8.4 to 0.8.7 last 2 weeks. Everything seem to be OK for 1 week. After that, sending and receving mail is very slow and often has request timeout. First I think my mail server is under heave load (RAM usage always at 95%) due to SPAM. I managed to add IP to blacklist (as you known from my previous thread). After restarting server, load is back to normal and I can add IP to blacklist and successfully tested. However, sending and receiving mail from roundcube webmail is still very slow and often get "request timeout".

Here are log on dovecot.log:

After some minutes, the web browser stop "sending message". Maybe account logged out before sending message...

Best regards,
Minh

It's impossible (not interested) for me or others to check your previous thread, so you'd better paste link in your post directly, or don't mention it if it's not related to this post.

Pasted Dovecot log is useless, it's just login/logout info, nothing related to your issue.
It's hard  for me to help troubleshoot without related log, so please try to extract related log and paste here.
