Is it permissible to open the messages of domestic workers for fear of finding pictures belonging to family members or other such problems?

Bringing foreign housemaids involves many Shariah prohibitions. It is authentically reported from the Prophet, peace and blessings be upon him, "Whoever listens to the conversation of a people while they dislike it, molten lead will be poured into his ear on the Day of Resurrection." If it is permissible to view housemaids' messages, then the viewer should limit themselves to searching only for what is feared to exist, and should not read the message or inspect its content if it does not contain anything that could cause harm.
