Not so - Fred108 only has one set of numbers in the name.

Yes, but the point is that from a pattern matching standpoint, for which you will need some algorithm which has to be -smart- and not take up much computing overhead, Fred108 and A24kJf32 are essentially equivalent. Such an algorithm that is also general enough to be useful is non-trivial.

Otherwise you need a rules-based system, and every time you see a new permutation, you need to add a new rule. I think Commungate Pro can do rules.

With SIMS, adding a new "rule" means adding a new router entry. I tried in the early days to track these and route them to error, but I gave up quickly - the possible permutations of what are almost random sequences was too large, not to mention the smattering of legit Fred108s that tended to make things difficult.
