this is the second time I asked this

I just switched from Thunderbird, which let through only a fraction of the spam I am now getting. Why do I get up to 4 copies of the same spam messages?

This shouldn’t be a problem caused by eM Client. If you have web access of your e-mail, please check on-line to see if this is the same on the server.

You are quite right, there are multiple copies on the Comcast server. This just started and must have coincided with my ditching Thunderbird for eMClient. Thanks for the tip.
