how to delete them ,bro

The password should normally work unencrypted. The only exception is when the password itself is base-64 encoded and has specific length (44 or 88 characters) - in this case NetXMS will think that it's something encripted by nxencpasswd - in this case the workaround is to actually encrypt it with nxencpasswd.
Also, double-check the "Login" field.

I try the password as plain text and encrypted with nxencpasswd ..

right click -> terminate

thanks, right click -> terminate is stand for delete these alarms in database?

You can select many alarms at once and select "Terminate" from right-click menu. And disabling event processing policy rules that you don't need would prevent these alarms from happening in the future.

The way NetXMS is built is that when something happenins (interface went down, threshold reached, etc...) it creates events (log of these can be seen in Event Log). Reaction to events is defined in Event processing policy (make sure you click "save" button when working with it).

Thank you brother, yes, here is the configuration;
One more question, how do I remove old history alerts if I disable these policies midway through? (history alert package install update etc)

Try issuing
debug nc 8
debug ncd.* 8
in Tools->Server Debug Console. Then try to send another email and show what you have in your server log (/var/log/netxmsd on Linux)
