Miss. Code § 51-31-117
All proceedings under this chapter are declared to be proceedings in rem. The notices for the organization of a drainage district hereunder and all subsequent notices herein provided for shall be sufficient as notices for the purposes stated, the organization of a district, and the issuance of district bonds as herein provided. The failure of the clerk to send a copy of any notice by registered mail to any nonresident, whose residence is known or unknown, shall not invalidate the proceedings for the organization of any drainage district hereunder or of bonds of the district issued under same; but the court or chancellor in vacation may adjourn the hearing of any case in order to cause other notice to be made, if in his discretion he thinks proper, in order to comply with the requirements of this chapter.
