Dotaz

 Dobrý deň ,
V svojom programe používam funkciu, ktorá spustí predvoleného
emailového klienta, vypíše text správy, vyplní sa predmet a príjemca.::

  os.startfile('mailto:tomasiol.sk?subject=Sprava&body=text')

Ak je text správy dlhší ako 2000 znakov tak mi vypíše !WindowsError
pristup bol odporen.

Nevie niekto ako by som to mohol vyriešiť?

Prostý mail

 Mírně zjednodušený příklad z Helpu::

  import smtplib

  odesilatel = "ilovepy@post.cz"
  prijemce  = "ilovepytoo@post.cz" 
  predmet="ahoj"

  # Add the From: and To: headers at the start!
  msg = "From: %s\r\nSubject: %s\r\nTo: %s\r\n\r\n" % (odesilatel, predmet, prijemce)
  zprava="Ahoj jak se mas. "*1000
  msg=msg+zprava
  print "Zprava: \n\n", msg
  print "\nZprava je dlouha", len(msg),"bitu\n"

  server = smtplib.SMTP('smtp.seznam.cz')     # zde zadejte svůj smtp server
  server.login('....','...')                  # vaše uzivatelské jmeno a heslo pro odesílání - někdy není tato autentizace potřeba
  server.sendmail(odesilatel, prijemce, msg)
  server.quit()
