I have multiple email addressed but a main for friends and family only. For years, I had little spam but this past 2 weeks I get at least 10 a day from the same place. They all use familiar names like "[email protected]." or "[email protected]." with subjects like "mailing error" or "undelivered mail". I never open them, I assume they are coming from the same place because they all have an attachment that is 73KB. They usually go into my junk mail folder but once in awhile they go in my regular folder. Very annoying, is there any way to trace these to see where they are coming from? I thought about going to a public library to open these to see what they are but I don't want to affect a library computer.
