Cannot send or save drafts.

[Bables55]

RainLoop version, browser, OS: Firefox, Vivaldi, Safari, Edge. Mac &Windows. Expected behavior and actual behavior: I type a message in the body to send an email and try to send or save a draft. However, often it cannot be sent or saved to a draft.

Steps to reproduce the problem: It is likely to occur when typed as follows. However, that is not certain.

NAME

I have even been able to send/save mail once I removed the hyphens. It is not the amount of text in the body of the text, nor the HTML or PLAIN format.

I have installed on two different servers and it occurs on both. I do not know for certain the cause of the outbreak.

CentOS 7 or 6, PHP 8.0.21, Rainloop 1.16.0
