The Reply-To header in comment reply notification emails was being manually formatted with quotes, similar to the From header. However, PHPMailer treats these headers differently: - From headers are set via `setFrom()`, which applies proper quoting and encoding internally. - Reply-To headers in core were added as custom headers via `addCustomHeader()`, which passes the value through `encodeHeader()` and escapes quotes a second time. This mismatch caused author names with quotes to be encoded as: Reply-To: \"Author\" <author@example.com> This commit fixes this issue. See Trac #49661
