Could you apply this patch and see what it logs then:

Changing login_max_connections doesn't affect anything because you're
using login_process_per_connection=yes.

The needed fd count is calculated from login_max_processes_count(pop3) +
login_max_processes_count(imap) + max_mail_processes.

So in your case 128+128+128.
