These days, I need to be extra-vigilant in terms of filtering possible spam and malware. I also get a substantial volume of spam comments and emails each day. As a result, it is almost certain that I am occasionally missing legitimate emails and comments, deleting them from spam folders that I don’t have time to check through manually, or never even seeing them because they are automatically blocked on a different basis.
The blog’s spam filtering systems are fairly sensitive to links, so if your comments are being eaten try posting them without links.
Similarly, for email, I am more likely to open an email from an unknown sender if it is in plain text (not HTML) and includes no attachments.
