Hi there,
The following error bothering me for a couple of days.

Code:
2013/06/13 15:40:11 [error] 12818#0: *2510 SSL_read() failed (SSL: error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac) 
while proxying and reading from upstream, client: xx.xx.xx.xx, server: 0.0.0.0:995, login: "user@domain.com", 
upstream: xx.xxx.xx.xx:7995 (xx.xx.xx.xx:51078-xx.xx.xx.xx:995) <=> (x.xx.xx.xx:43485-xx.xx.xx.xx:7995)
When receiving mail via Outlook with attachment - drops connection to the server.
I noticed that attachments of up to 10mb pass above them.
In the configuration, there are no limits.
I also noticed that after 10 attempts to fetch mail - is taken and there are no errors in the logs
Nginx supports SSLv3.


Code:
zimbra@v033:~/log$ zmprov gacf zimbraReverseProxySSLCiphers
zimbraReverseProxySSLCiphers: SSLv3:SSLv2:TLSv1:MD5:HIGH
Zimbra Version:
8.0.3

System version:
Ubuntu 12.04

Openssl version:
openssl 1.0.1c-3ubuntu2

I have no idea what could be the problem. Please help, or directed at solving the problem.
Google ended already prompting me;/
Thank you in advance for any help!
