To replacing the leading '.' in an quoted-printable encoded mime part to avoid obscure SMTP bug.
Performance Implications
This change incurs an additional memory copy for the mime body. This might be of concern for very large mime bodies. We have the option of scanning the body for leading '.' if none are found we can return the body unmodified. This trades off memory consumption for additional CPU usage per message generated.
