Hello,
I have a strange header which causes Roundcube Webmail 1.2.0 to hang. Could you please investigate why and fix this in the next version? I have removed the ips and the domains from the message but it should produce the same results and I can confirm it was not the body but the header which caused the issue. I had to do bunch of traffic sniffing between the rc<>dovecot until I figured out that this is the root cause. If you drop this file into a user's Maildir/cur/ folder and go there with RoundCube it should reproduce the same issue (as a body message it will do nothing so safe to send it to the list):
cat ./1472824758.M248861P20044.server1,S=3027:2,S

I'm unable to reproduce.
Disable all plugins, enable imap_debug in Roundcube. Maybe this will give you some hints. What exactly "it hangs" means? Maybe dovecot hangs, not Roundcube? Any errors in log?
Hello,
Well I can easily reproduce that error any time even using the censored out header file I have sent you. Just copy pasting that message into a new file like
1472824758.M248861P20044.server1,S=3063:2,S
and going there in roundcube.

I am certain it is a roundcube issue, it is like rc would be expecting some data from the server and it is keep bashing the imapproxy or dovecot for it (almost like DOS).
Enabling the imap log was a good idea. I did not know about this just $config['debug_level'] = 8; which did not help.
So I attaching the first 1k line of the log, it grow to 1.5MB in seconds but it does the same thing over and over.

Something's trying to move the message to spam and it fails. So, the bug is in imap as you see above, but I think you're using some plugin, because Roundcube does not move messages to to Spam when accessing them. So, this might be caused by some plugin.
I also think that maybe you hit another issue. Is your session_lifetime setting a very big value? Set it to something sensible, like 60.
Use debug_level=1.
