XF 1.5 Mass Email Issue... Google SMTP

[AppleAndMango]

Hello!

I tried to send a mass email out this morning though I received the following error... I've tried using Google's SMTP server using SSL/TSL having the same error message.

Spoiler: Error

ErrorException: Email to removed@hotmail.com failed: fwrite(): SSL operation failed with code 1. OpenSSL Error messages: error:140D00CF:SSL routines:SSL_write:protocol is shutdown - library/Zend/Mail/Protocol/Abstract.php:324

I have found this..

But I'm still having no luck, as far as I'm aware I've sent test emails, password reset emails they seem to work..

It just sounds like the connection was closed when attempting to send the mail. Is this happening for just a few users or many?

Only appears to be happening when I'm trying to send many.
