hello,

I've recently upgraded from 0.8.8h (that included settings plugin) to 1.0.0 and now cacti no longer sends email. not even the most basic setting (SMTP).

i used SMTP in the old version and it worked fine. (it doesn't require authentication or SSL, user and pass fields are left empty)

the error message is:

Checking Configuration...
Method: SMTP
Ping Results: SMTP error: Authentication failed: 501 5.7.3 Cannot decode arguments
Message Not Sent due to ping failure.

But SMTP works fine, i have ping and port 25 connectivity to mailserver :

[root@adcacti02 cacti]# telnet xxxxxxxxxx.internal.vodafone.com 25

Connected to xxxxxxxxxx.internal.vodafone.com.

surprisingly, there are no logs in cacti.log, even with the highest debug setting.
