it seems the basic POSIX do not support matching groups:
https://en.wikibooks.org/wiki/Regular_Expressions/POSIX_Basic_Regular_Expressions
so your REGEX From:^(user1|user2|user3)@domain.tld$ will never work

From the man page for clamav-milter.conf
<https://linux.die.net/man/5/clamav-milter.conf>
Whitelist STRING
This option specifies a file which contains a list of basic POSIX regular expressions. Addresses (sent to or
from - see below) matching these regexes will not be scanned. Optionally each line can start with the string
"From:" or "To:" (note: no whitespace after the colon) indicating if it is, respectively,
the sender or recipient that is to be whitelisted. If the field is missing, "To:" is assumed. Lines
starting with #, : or ! are ignored.
However, with the whitelist set as defined in my original message,
emails [email protected] are still scanned and, indeed, flagged as
infected. I would like messages from emails that match the whitelist to
be excluded from the scan.

okay and what is your problem now? Didn't also understand what you want
to do with your whitelist and what should happen then?
