I think we can do it like this:
mysql> select name from dbmail_mailboxes where binary name regexp
'[lL][iI][sS][tT][eE][nN]/[uU][bB][uU][nN][tT][uU]';
+---------------------+
| name |
+---------------------+
| Listen/Ubuntu |
+---------------------+
Horribly ugly, but MySQL doesn't support regular expression
transformations. Before sending a mailbox to be looked up,
convert it into the self-matching case insensitive form.
The same syntax in PostgreSQL uses ~ instead of REGEXP. PostgreSQL also
has a regexp_replace function that probably could be used to actually
produce the proper lowercase form, skipping whatever's between non
greedy pairs of & - ... but whatever.
