Switch MAILER_SMTP_FROM_EMAIL and MAILER_SMTP_USER defaults and fix CLA signing script

[kevinam99]

Aims to fix issue #356 with the same title

Does this require any tests to be updated?

[kevinam99]

Also fixed the issue with the CLA signing script. Was getting this error

base64: invalid option -- w
Usage: base64 [-Ddh] [-b num] [-i in_file] [-o out_file]
-b, --break break encoded string into num character lines
-Dd, --decode decodes input
-h, --help display this message
-i, --input input file (default: "-" for stdin)
-o, --output output file (default: "-" for stdout)

Oh, fabulous, thanks for taking this on! I’ll include this in the next release and update the website docs accordingly.

Also thanks for signing the CLA and reporting the issue with the base64 tool. It looks like there is an incompatibility between the macOS version (which you were probably using) and the GNU versions. While the macOS version has the -b parameter, GNU versions have -w But I’ll fix that after merging your PR.

Yeah, probably a macOS thing so I went ahead and removed the flag altogether. That too seems to achieve the same result
