You can use the FIELDORDER resource.
In the mailing list which I want to archive by mhonarc,
some X-*** headers, such as X-Mailer, X-ML-Name, X-MLServer are added to
the message. In these X-*** headers are removed by default. But I would
like to remain X-Sequence: header.
I tried to find information in the mailing list archive but failed.
How should I write rcfile ?
