Error when sending e-mail, based on the "from" user's name

[rdunlop]

We had a convention with a short name of "We are currently full, if you wish to be on the waiting list email\r\n eucwinter@gmail.com - Winter EUC'18"

This was causing e-mail failures with errors like "Aws::SES::Errors::InvalidParameterValue Local address contains control or whitespace".

At first I thought it was the ' character, but that isn't it. I'll have to figure out whether it's the length of the string, or some other reason. I'm guessing it's the \r\n, but I am not certain.

We should put into place some sort of guard/filter for this...and also identify where else it may occur.
