POP3 header over the serial port. The POP3 header contains the From, Cc and Subject fields.

#POP3PORT – Set POP3 Server Port 
Description:  To reach the POP3 server, the TCP/IP stack software must know the port of the POP3 server 
used for retrieving email.

network infrastructure configuration including firewalls, proxy or specific TCP port translation 
settings.

  AT#POP3PPORT? Read or display the current setting (or AT#VPOP3, AT#VALL). 
Values:  5 digits (each digit between 0 and 9 inclusive). Note that numbers above 65,535 are illegal as the 
port identification fields are 16 bits long in the TCP header.  
Default:  110
