No, the cleanup(8) server virtual lookup key and value are in rfc822
quoted form, and will correctly process:
[email protected]
"internal,comma"@example.com,
"internal whitespace"@example.net,

See src/cleanup/cleanup_map1n.c around line 118:
quote_822_local(state->temp1, argv->argv[arg]);
if ((lookup = mail_addr_map(maps, STR(state->temp1), propagate)) != 0) {
...
}
Of course the address may not get that far, because the SMTP server
uses the internal form of the address when doing recipient validation:
static int check_rcpt_maps(SMTPD_STATE *state, const char *recipient,
const char *reply_class)
{
...
if (MATCH(rcpt_canon_maps, CONST_STR(reply->recipient))
|| MATCH(canonical_maps, CONST_STR(reply->recipient))
|| MATCH(virt_alias_maps, CONST_STR(reply->recipient)))
return (0);
One could argue that the SMTP server should use the external form of the
recipient for these lookup, to match downstream behaviour in cleanup(8)...
