Hi,
Above, in your code, the answer to your question.
I suggest this code (not tested - I didn't check neither the poplib - but
gives some ideas like instance variables, default args, ...):
class PopMailServer:
def __init__ (self, host = "", user = "", password = "*"):
self.host=host
self.user=user
self.password=password
self.mails=[]
pop=poplib.POP3(self.host)
pop.user(self.user)
pop.pass_(self.password)
countMails=len(pop.list()[1])
for i in range(countMails):
self.mails.append(pop.retr(i+1)[1])
pop.quit()
print "Antal mails: %d\n" % len(self.mails)
