Here's an incomplete list of more or less related categories:

Parent categories[edit]

Category:E-mail(edit talk links history)
Category:Authentication methods(edit talk links history)

Category:E-mail authentication allows to reduce the number of categories for articles belonging to both categories.

Subcategories[edit]

Category:PGP(edit talk links history)

That's not exactly true, OpenPGP is also used in contexts unrelated to E-mail like Usenet. Adding only some articles in Category:PGP to Category:E-mail authentication instead of the whole Category:PGP might be better.

Related categories[edit]

The spam categories are as expected messy. Today spam is used in many contexts not more limited to E-mail. Historically the term was only used for Usenet spam. In E-mail the technical terms are Unsolicited Bulk E-mail (UBE) or Unsolicited Commercial E-mail (UCE) - not all UBE is also UCE and vice versa, and some UBE is not necessarily spam.
