Enterprise Manager - E-Mail alerts not triggering

Hi, i have a EM VE and i configured a Device Alert to send a e-mail when some of the monitored devices changes status (Active, Standby, Offline, Force Offline). The EM register the event in the alert history but the notification e-mail is not being sent. I have this input in the EM log:

 

"Error invoking sendmail, popen exit code is 1 - check stdout or /var/log/emalertd.out for more info."

 

Here is the output from /var/log/emalertd.out:

 

Traceback (most recent call last): File "/etc/em/simplemail.py", line 115, in ? main() File "/etc/em/simplemail.py", line 112, in main sendmail(options, args) File "/etc/em/simplemail.py", line 59, in sendmail s.login(options.username, options.password) File "/usr/lib/python2.4/smtplib.py", line 583, in login raise SMTPException("No suitable authentication method found.") smtplib.SMTPException: No suitable authentication method found.

The weird thing is that i have a SMTP configured and it's working from reports (Capacity Planning, Unused LTM Object, etc). Current version is 3.1.1 HF 8.
