If you use the send method with an SMTP server, you don't want to change this.
While RFC 2045 mandates CRLF as a lineseperator, there are some edge-cases where this won't work.
When passing the E-Mail string to a unix program which handles communication with the SMTP server, some (i.e. qmail)
expect the system lineseperator (LF) instead.
Notably, the google mail REST API will choke on CRLF lineseps and produce strange emails (as of 2024).
Do not change this after calling other methods, since it might break presaved values.
