For reasons unknown, I can't post to a lot of groups because While I
can download the headers,, they're not in the newsgroups listing.

As we used to say "Can I get an interpretation?"

I tried copying these into Agent, but I think the {} brackets are
causing a syntax error.
If you could tell what they are supposed to be doing, that might
help. E.G the first one I got to work was:
Subject: {^[a-z\d]}
which I read as "at the beginning of line, match any alpha char a to
z, and any digit."
It works for the most part.
{I had to look up \d. and now I think I know what the {15} in the
original part was.) The second and third filters, my system tells me
the syntax is invalid.

I can't tell you what they're supposed to do, but I can tell you
they're not written for Agent's implementation of Regular
Expressions.

The Expressions are Regular, but not Standard. Agent's is one of the
less full-featured variations of REs.

I can't tell either. If I could figure what it is doing, I
_might_ be able to work around it.

Agent can handle some RegEx, so I'm hopeful.

See: https://regexr.com/ for a possible regex explainer tool.
Copy-paste your regex into the Expression field and hover your mouse
pointer over the elements to get descriptions of what the expression
element is doing.

An Agent message filter is not a regex-like filter until it is
enclosed in braces. Therefore you must write:
Subject: {^[a-z\d]{15}} in order for it to be a valid Agent regex.

The backslash '\' character is always an escape character, forcing
Agent to accept the character following the backslash as a literal
character, no substitution or interpretation is performed. So where a
special character like ^ or . is used within an Agent regex, you would
escape it first (e.g. \^ or \.).

Positional characters (^ and $) are only effective inside an Agent
regex so they must be inside braces when used.

Generally, avoid using regex in Agent except when conventional filters
can't be effective.

For example, the filter message-id: googlegroups.com should be
preferred over message-id: {googlegroups\.com} since it is faster and
does the job just as effectively as the regex version.

Unfortunately this particular one will still _not_ be a valid Agent
regex even when enclosed in braces. Agent does not support the {15},
nor the \d.

For the '\d' in the example in question, the backslash '\' character
is meant to mean the 'd' is *not* a literal character.

For the meaning of '\d', see the very recent post "More Info On Agent
Filtering - Perl Regular Expression Tutorial". (But note that Perl
regular expressions do not work in Agent.)
