+"""
+   Have a look at the incoming APRS message and check if it
+   contains a message no which does not follow the APRS
+   standard (see aprs101.pdf chapter 14)
+   but rather follow the new format
+   http://www.aprs.org/aprs11/replyacks.txt
+
+The following assumptions apply when handling APRS messages in general:
+
+Option 1: no message ID present:
+    send no ACK
+    outgoing messages have no msg number attachment
+        Example data exchange 1:
+        DF1JSL-4>APRS,TCPIP*,qAC,T2PRT::WXBOT    :94043
+        WXBOT>APRS,qAS,KI6WJP::DF1JSL-4 :Mountain View CA. Today,Sunny High 60
+
+        Example data exchange 2:
+        DF1JSL-4>APRS,TCPIP*,qAC,T2SPAIN::EMAIL-2  :jsl24469@gmail.com Hallo
+        EMAIL-2>APJIE4,TCPIP*,qAC,AE5PL-JF::DF1JSL-4 :Email sent to jsl24469@gmail.com
+
+Option 2: old message number format is present: (example: msg{12345)
+    Send ack with message number from original message (ack12345)
+    All outgoing messages have trailing msg number ( {abcde ); can be numeric or
+    slphanumeric counter. See aprs101.pdf chapter 14
+        Example data exchange 1:
+        DF1JSL-4>APRS,TCPIP*,qAC,T2SP::EMAIL-2  :jsl24469@gmail.com Hallo{12345
+        EMAIL-2>APJIE4,TCPIP*,qAC,AE5PL-JF::DF1JSL-4 :ack12345
+        EMAIL-2>APJIE4,TCPIP*,qAC,AE5PL-JF::DF1JSL-4 :Email sent to jsl24469@gmail.com{891
+        DF1JSL-4>APOSB,TCPIP*,qAS,DF1JSL::EMAIL-2  :ack891
+
+        Example data exchange 2:
+        DF1JSL-4>APRS,TCPIP*,qAC,T2CSNGRAD::EMAIL-2  :jsl24469@gmail.com{ABCDE
+        EMAIL-2>APJIE4,TCPIP*,qAC,AE5PL-JF::DF1JSL-4 :ackABCDE
+        EMAIL-2>APJIE4,TCPIP*,qAC,AE5PL-JF::DF1JSL-4 :Email sent to jsl24469@gmail.com{893
+        DF1JSL-4>APOSB,TCPIP*,qAS,DF1JSL::EMAIL-2  :ack893
+
+Option 3: new messages with message ID but without trailing retry msg ids: msg{AB}
+    Do NOT send extra ack
+    All outgoing messages have 2-character msg id, followed by message ID from original message
+    Example: 
+    User sends message "Hello{AB}" to MPAD
+    MPAD responds "Message content line 1{DE}AB" to user
+    MPAD responds "Message content line 2{DF}AB" to user
+
+    AB -> original message
+    DE, DF -> message IDs generated by MPAD
+
+        Example data exchange 1:
+        DF1JSL-4>APRS,TCPIP*,qAC,T2NUERNBG::WXBOT    :99801{AB}
+        WXBOT>APRS,qAS,KI6WJP::DF1JSL-4 :Lemon Creek AK. Today,Scattered Rain/Snow and Patchy Fog 50% High 4{QL}AB
+        DF1JSL-4>APOSB,TCPIP*,qAS,DF1JSL::WXBOT    :ackQL}AB
+        WXBOT>APRS,qAS,KI6WJP::DF1JSL-4 :0{QM}AB
+        DF1JSL-4>APOSB,TCPIP*,qAS,DF1JSL::WXBOT    :ackQM}AB
+
+        Example data exchange 2:
+        DF1JSL-4>APRS,TCPIP*,qAC,T2SPAIN::EMAIL-2  :jsl24469@gmail.com Hallo{AB}
+        EMAIL-2>APJIE4,TCPIP*,qAC,AE5PL-JF::DF1JSL-4 :Email sent to jsl24469@gmail.com{OQ}AB
+        DF1JSL-4>APOSB,TCPIP*,qAS,DF1JSL::EMAIL-2  :ackOQ}AB
+
+Option 4: new messages with message ID and with trailing retry msg ids: msg{AB}CD
+    We don't handle retries - therefore, apply option #3 for processing these
+    the "CD" part gets omitted and is not used 
+
+        Example data exchange 1:
+        DF1JSL-4>APRS,TCPIP*,qAC,T2CZECH::WXBOT    :99801{LM}AA
+        WXBOT>APRS,qAS,KI6WJP::DF1JSL-4 :Lemon Creek AK. Today,Scattered Rain/Snow and Patchy Fog 50% High 4{QP}LM
+        DF1JSL-4>APOSB,TCPIP*,qAS,DF1JSL::WXBOT    :ackQP}LM
+        WXBOT>APRS,qAS,KI6WJP::DF1JSL-4 :0{QQ}LM
+        DF1JSL-4>APOSB,TCPIP*,qAS,DF1JSL::WXBOT    :ackQQ}LM
+        Example data exchange 2:
