I have an problem with this little script. The script is in the zope file structure and it is an -Script (Python)- The script should send 2 emails over the mailhost, but it sends 4 emails. I have test this with maildrophost product too, same problem. I have test it on Zope 2.10.0 and Zope 2.64. The problem is the same - everytime. This script produce the error: #### start #### for i in range(2): subj = str(i) + ' range python' context.MailHost.send('range test with python', "rec@mail.com", "sender@mail.com", subj) #### end #### This script produce no error: #### start #### for i in range(2): subj = str(i) + ' range python' context.MailHost.send('range test with python', "rec@mail.com", "sender@mail.com", subj) return 'eof' #### end #### So if i make a return (not in the loop) the script works fine. Can anybody tell me why? It feels like that there are any spaces in the script and zope/python did not work correctly when there is no other procedure after the for loop. I dont understand why he calls the loop two times and produce 4 emails. There is no transactional error in the error_log. thx for help
