Using SpamAssassin 3.4.5 (2021-03-20)

Perhaps memory fails, but was there not, once, a standard rule that detected 
non alpha characters in
sender name?  The domain/provider is not of interest for this question.

Such as this item (not the actual sender name)

        *  1.0 FREEMAIL_FROM Sender email is commonly abused enduser mail
        *      provider
        *      [abcd531if7[at]gmail.com]

It's not currently used in any scored base rules, though.

Related base rules:

FROM_STARTS_WITH_NUMS
__FROM_ALL_NUMS
__TO_ALL_NUMS
__FM_TO_ALL_NUMS

  Back in 1969 the technology to fake a Moon landing didn't exist,
  but the technology to actually land there did.
  Today, it is the opposite.                               -- unknown
