> camel-mail - MimeMultipartDataFormat unmarshal does not filter the
> mail.smtp/mail.smtps header namespace

> CAMEL-23522 extended MailHeaderFilterStrategy so that the inbound path also
> filters the mail.smtp. and mail.smtps. prefixes, not just Camel*/camel*:
> String[] inFilter = Arrays.copyOf(CAMEL_FILTER_STARTS_WITH,
> CAMEL_FILTER_STARTS_WITH.length + 2);
> inFilter[CAMEL_FILTER_STARTS_WITH.length] = "mail.smtp.";
> inFilter[CAMEL_FILTER_STARTS_WITH.length + 1] = "mail.smtps.";
> setInFilterStartsWith(inFilter);
> MimeMultipartDataFormat, which CAMEL-23891 gave a header filter for the
> Camel* namespace, still holds a plain DefaultHeaderFilterStrategy:
> private final HeaderFilterStrategy headerFilterStrategy = new
> DefaultHeaderFilterStrategy();
> used by copyNonStandardHeaders() (line 283) when headersInline unmarshal
> copies MIME headers onto the exchange. DefaultHeaderFilterStrategy only knows
> Camel*/camel*, so the mail.smtp./mail.smtps. namespace that CAMEL-23522
> deliberately filters on the consumer path is not filtered here.
> Proposal: use MailHeaderFilterStrategy (or a strategy configured with the
> same inbound prefixes) in MimeMultipartDataFormat so both entry points agree
> on the filtered namespace, with a test covering a mail.smtp.* header on
> unmarshal. Backport alongside the CAMEL-23891 backports (4.14.x, 4.18.x).
