There won't be any, because in both mutt and neomutt tcp:25 is the
default for smtp.
Specifically, smtp_fill_account() at smtp.c shows this:

  if (!account->port)
  {
    if (account->flags & MUTT_ACCT_SSL)
      account->port = SMTPS_PORT;
    else
    {
      static unsigned short SmtpPort = 0;
      if (!SmtpPort)
      {
        struct servent *service = getservbyname("smtp", "tcp");
        if (service)
          SmtpPort = ntohs(service->s_port);
        else
          SmtpPort = SMTP_PORT;
        mutt_debug(3, "Using default SMTP port %d\n", SmtpPort);
      }
      account->port = SmtpPort;
    }
  }

And getservbyname(3) will return port 25 for smtp, because it's the port
designated for smtp in /etc/services.
Of course, they *could* use "submission" (which is tcp:587) at that code
instead of "smtp", but they did not.
