Losing Subject: Line on Sent Mail

[citechnical]

I'm losing the subject: of the emails being sent from RoundCube 1.1.0 on CentOS 7. Anyone know why? I couldn't find anything anywhere and I've added a bug to Trac but I probably should have asked here first.

I'll send anything, logs, configs, etc. if someone can help.

Thanks,

David L. Whitehurst
