We monitorize a lot of ARCServe D2D status (copy, fusion,etc) with one mailbox where all the mails goes to.
In past weeks, the sensor worked great, but right now, all of them are down with error "login failed". This is very weird, 'cause the mailbox does not changed in anyway. I've changed the mailbox's password. I've reconfigured the sensor's credentials, the sensor was fine for a few seconds and then has fell again. Very strange.
And new credentials seems to be not valid for any of them.
Any ideas???
