A plurality of incoming mail mailboxes each include a sampler to sample air from a letter that is tested using a first sensor. Source information corresponding to hazard flagged mail pieces is utilized to block mail from that source at other mailboxes. ## Claims ### Claim 1 A system of incoming mail receptacles for detecting hazards in a mail piece comprising: a plurality of incoming mail receptacles each including a contaminant detection hazard detector, a communications system, and a source detection system for providing suspect source information when a hazard is detected; and a server connected to the plurality of incoming mail receptacles for receiving suspect source data and communicating the suspect source data to the incoming mail receptacles, wherein the suspect source data is determined using the suspect source information, wherein the suspect source information includes at least one fingerprint. ### Claim 2 (depends on 1) The system of claim 1 further comprising: a secure network connection between each incoming mail receptacle and the server. ### Claim 3 (depends on 1) The system of claim 1 further comprising: an image scanner for scanning the face of a mail piece. ### Claim 4 (depends on 1) The system of claim 1 wherein the source information comprises a meter number. ### Claim 5 (depends on 1) The system of claim 1 wherein the source information comprises a scan image. ### Claim 6 (depends on 1) The system of claim 1 wherein the source information comprises Optical Character Recognition data. ### Claim 7 (depends on 1) The system of claim 1 wherein the source information comprises a handwriting signature. ### Claim 8 (depends on 1) The system of claim 1 wherein the contamination detector hazard detector comprises: a segregated incoming mail air sampler for collecting an air sample having an incoming mail opening and a lockable door for the opening; a mail piece transport system for feeding the mail piece through the sampler; a movable surface for applying force to an edge of the mail piece to form a pillow deformation in the mail piece; a flattener for flattening the pillow deformation to collect the air sample; a hazard detector to test the air sample and for providing a hazard indication; and a transport mechanism for moving the mail piece from the air sampler into a collection chamber if no hazard is detected. ### Claim 9 A method for coordinated hazard detection in a mail system having a plurality of incoming mail receptacles with hazard detection systems connected to a central server comprising: detecting the presence of a mail piece; detecting source information relating to the mail piece; testing the mail piece for hazards to determine an initial mail piece quarantine condition; and alerting the central server upon detection of a hazard and providing source information to the central server, wherein the source information is associated with the detection of the initial mail piece quarantine condition, wherein the source detection includes detecting at least one fingerprint. ### Claim 10 (depends on 9) The method of claim 9 wherein the source detection includes detecting a meter serial number. ### Claim 11 (depends on 9) The method of claim 9 wherein the source detection includes detecting a return address. ### Claim 12 (depends on 9) The method of claim 9 wherein the source detection includes detecting a handwriting sample. ### Claim 13 (depends on 9) The method of claim 9 further comprising: providing hazard information to the central server. ### Claim 14 (depends on 9) The method of claim 9 further comprising: alerting a response team to the hazard condition. ### Claim 15 (depends on 9) The method of claim 9 further comprising: sealing the incoming mail receptacle if a hazard is detected. ### Claim 16 (depends on 9) The method of claim 9 further comprising: redistributing the source information from the server to at least one incoming mail receptacle. ### Claim 17 (depends on 9) The method of claim 9 further comprising: distributing source exclusion information from the server to at least one incoming mail receptacle based upon the source information received at the server. ### Claim 18 A system of incoming mail receptacles for detecting hazards in a mail piece comprising: a plurality of incoming mail receptacles each including a contaminant detection hazard detector, a communications system, and a source detection system for providing suspect source information when a hazard is detected; and a server connected to the plurality of incoming mail receptacles for receiving suspect source data and communicating the suspect source data to the incoming mail receptacles, wherein the suspect source data is determined using the suspect source information, wherein at least one of the incoming mail receptacles includes a contaminant detection hazard detector; a fingerprint enhancing substance dispenser for dispensing a fingerprint enhancing substance for use in detecting fingerprints if a hazard is detected; and a fingerprint scanning system for scanning fingerprints on the mail piece if a hazard is detected. ### Claim 19 (depends on 18) The mail receptacle of claim 18 wherein the fingerprint enhancing substance includes crazy glue fumes.
