Hector Urtubia Aug 2003 # Example (see the test function at the end of this file) # Imports import errno import re import socket import sys try: import ssl HAVE_SSL = True except ImportError: HAVE_SSL = False __all__ = ["POP3","error_proto"] # Exception raised when an error or invalid response is received: class error_proto(Exception): pass # Standard Port POP3_PORT = 110 # POP SSL PORT POP3_SSL_PORT = 995 # Line terminators (we always output CRLF, but accept any of CRLF, LFCR, LF) CR = b'\r' LF = b'\n' CRLF = CR+LF # maximal line length when calling readline().
