[ghost]

Hi all!
After updating our rocket.chat from 0.39 to the latest 0.40.1 version and updating node js from 0.10.40 to 4.5 we got chat server process crash periodically with error:

2016-09-22 18:36:54 252: Error: 139654647129984:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number:../deps/openssl/openssl/ssl/s3_pkt.c:362:

We use SSL and nginx config from documentation.

We don't sending any emails from rocket.chat. Email section doesn't configured.

In the error log only this:
2016-09-22 19:05:43 339: Error: 140486012131200:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number:../deps/openssl/openssl/ssl/s3_pkt.c:362:
at Error (native)

[engelgabriel]

Someone in your GENERAL channel has email alerts turned on, and your email server setting is incorrect.

[engelgabriel]

The PR #4416 will prevent the server from crashing.
