notice through post-office

When the party to be affected by the notice, resides in a different place from the holder, the notice may be sent by the mail to the post-office nearest to the party entitled to such notice... If he was in the habit of receiving his letters through a more distant post-office, and that circumstance was known to the holder, or party giving the notice, that might be the more proper channel of communication, because he would be most likely to receive it in that way; and it would be the ordinary mode of communicating information to him, and therefore evidence of due diligence.
