Initially Mail.com did a fine job of isolating spam mails because there were few incoming to deal with. However, in the last few months I have gotten a ton of spams because of the failure of an organization to shield its e-mails sent to members. I suspect there is a limit to how many spam domains and addresses Mail.com can retain in memory. I am getting many more in my inbox and suspect that the system has reached the limit of its capacity to filter incoming emails through 1000s of previous spam sources. I will need to open a new email account to get out of this bad situation.
