Without more code, it's impossible to tell if there is anything
peculiar in your usage of the lib. Maybe you close your connections to
fast to see several open?
Here's the relevant stuff from my (python2.6) code:
CONCURRENCY = 3
def threadProcessRecipient():
# Each thread has its own SMTP connection
smtpserver = smtplib.SMTP(SMTPSERVER)
# Each thread pulls a recipient entry from the queue to process and
loops until the queue is empty.
try:
recipientData = recipientQueue.get_nowait()
except Queue.Empty:
recipientData = None
while recipientData:
message = prepareMessage()
sendMail(senderEmail, recipientEmail, message, smtpserver)
recipientQueue.task_done()
try:
recipientData = recipientQueue.get_nowait()
except Queue.Empty:
recipientData = None
smtpserver.quit()
if __name__ == '__main__':
THREADS = []
for i in range(CONCURRENCY):
THREADS.append(threading.Thread(target=threadProcessRecipient))
for thread in THREADS:
thread.run()
for thread in THREADS:
thread.join()
