Original GitHub issue: https://github.com/axllent/mailpit/issues/535

According to RFC2396 Appendix E angle brackets are recommended for text/plain emails to recognize potential spaces in between the URL

In the case of mailpit, spaces are not being recognized and the presence of angle brackets are pretty much ignored
