507	Mail SSL not supporting EC Ciphers	Andreas Brörken		"The mail_ssl module does not support ciphers that are using Elliptic Curves. 

I'm using nginx on my server both as a mail reverse proxy and a web server which are both secured with SSL. When I run a cipher scan against that server, the EC ciphers only work for HTTP, but not for the mail module.

The output for HTTP is this: 

prio  ciphersuite                  protocols  pfs_keysize
1     ECDHE-RSA-AES256-GCM-SHA384  TLSv1.2
2     ECDHE-RSA-AES128-GCM-SHA256  TLSv1.2
3     DHE-RSA-AES256-GCM-SHA384    TLSv1.2
4     DHE-RSA-AES128-GCM-SHA256    TLSv1.2

The output for IMAP SSL is only this.

prio  ciphersuite                protocols  pfs_keysize
1     DHE-RSA-AES256-GCM-SHA384  TLSv1.2
2     DHE-RSA-AES128-GCM-SHA256  TLSv1.2

Both modules have identical configuration for SSL and the used ciphersuite. I attached the config I am using at the moment."	defect	closed	major		nginx-module	1.5.x	fixed	mail SSL EC cipher elliptic curve		Linux <Server-Name> 2.6.32-431.5.1.el6.x86_64 #1 SMP Wed Feb 12 00:41:43 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.4.5
