For two or three months I've been getting various error messages when I try to download my e-mail from the server. I first thought it was my Outlook Express program getting worn out, so I switched to Thunderbird, as the wave of the non-OE future.
Now I often as not get this:
Sending of password did not succeed. Mail server pop.midtel.net responded: User: denno Domain: midtel.net, Too many login attempts, try again later. Setting g_bad_login ip=18.104.22.168
My ISP tells me that some program or malware on some device in the house is apparently trying to sign on (frequently) with perhaps the wrong password, which causes their safelocks to bar my account temporarily.
I've made sure OE is not canvassing for downloads at all, on startup (I open it to refer to saved messages) or every 30 minutes or anything.
A basic Malwarebytes scan shows nothing.
There are two other "devices" in the house: my wife's computer, on which I only VERY occasionally check my mail, and then by signing in online; and her tablet. When we were in Europe I set up some kind of mail account on that, which did not seem to work. Or maybe it was that I couldn't figure out how; in any event , I checked my mail, again, by signing in online.
