Just today a buyer reported that my reply to him ended up in his spam folder. Concerned by this, I sent an email to my Yahoo! account and that one disappeared somewhere. The one I sent to gmail, however, got there quickly. I may be overreacting and, perhaps, it is a coincidence that Yahoo just happens to be slow at the moment. But I am concerned.
I have a general feeling that spammers became so good at making their messages look legitimate, that [poor] spam filters flag even completely innocent stuff as spam. This sending email by regular people who own their mailservers (as opposed to gmail and such) becomes more and more risky and impossible, in other words, email is quickly being undermined by spammers and filters to being unreliable and flaky. That is, now the damage from spam is not only in unwanted messages, but also in email lost due to sloppy filtering. I looked up my PC (75.146.106.188 on static IP from Comcast) and my mailserver (65.182.171.162 hosted in a datacenter) and did not find any RBL records to match. Any thoughts? i
